The PIAS (protein inhibitor of activated STAT) proteins play a crucial role as transcriptional coregulators in various cellular pathways, including the STAT, p53 and the steroid hormone signaling pathway. The PIAS protein family includes at least five evolutionarily conserved genes, including PIAS2. The major function of the PIAS proteins is the control of gene transcription and can also act as small ubiquitin-like-modifier (SUMO) E3 ligases. PIAS2 binds specifically to STAT4 following IL-12 stimulation and inhibits STAT4-mediated gene activation in human T cells. PIAS2 is a potent transcriptional activator of Bcl-2, but together with Bcl-6 can suppress the expression of Bcl-2.

The RAN binding protein 10 (RANBP10) is a cytoplasmic guanine nucleotide exchange factor that shares high sequence similarity to the MET-interacting protein RANBP9. RANBP10 is expressed in the cytoplasm of mature megakaryocytes (MKs) and platelets where it localizes to polymerized noncentrosomal microtubules. RANBP10 possesses guanine nucleotide exchange factor activity towards RAN, a GTPase involved in nucleocytoplasmic traffic, spindle formation at mitosis, and nuclear envelope assembly during telophase, suggesting that RANBP10 may also be involved in these activities. RANBP10 depletion in vitro caused the disturbance of polymerized filaments in MKs and platelets in RANBP10-null mice exhibited disorders in microtubule filament numbers and localization, indicating that RANBP10 may play a significant role in maintaining microtubule dynamics.

Prosapip2 (TBKBP1) is essential for signal transduction during viral infection thus plays a major role in the TNF/NF-kB pathway. It is an adaptor protein that constitutively binds TBK1 (TANK-binding kinase) and IKBKE and may play a role in antiviral innate immunity. Prosapip2 is a 615 amino acid adaptor protein belonging to the fibrillar collagen family, consisting of trimers of identical alpha 1 chains which are linked to each other by interchain disulfide bonds. It has a ubiquitous expression with highest levels in ovary, followed by the neuronal system. Prosapip2 binds to TBK1 and helps in the activation of IRF3 which controls the expression of antiviral genes during infection. Recent studies show that Prosapip2 is an interaction partner of ProSAP2/Shank3 and actin, suggesting a role as a linker molecule between postsynaptic density and the cytoskeleton.

Matrilin (MATNs) are a family of non-collagenous extracellular matrix proteins consisting of four known members that have been proposed to play key roles in the formation of both collagen-dependent and collagen-independent filamentous networks. Members of the matrilin family all share a structure made up of von Willebrand factor A domains, epidermal growth factor-like domains and a coiled coil alpha-helical module. MATN1 and MATN3 are expressed mainly in cartilage, while MATN2 and MATN4 occur in a wide variety of extracellular matrices such as embryonic kidney, lung, bone, cartilage and nervous system. The matrilin genes are strictly and differently regulated and their expression may serve as markers for cellular differentiation. MATN4 could serve as an odontoblast differentiation marker, e.g. in odontoblast stem cell research.

The TCF3 gene, also called E2A, encodes two basic helix-loop-helix (bHLH) transcription factors, E12 and E47, through alternative splicing. These transcription factors are involved in mediating canonical Wnt signaling, which is very important in a diverse array of cellular functions such as stem cell proliferation, self-renewal, activation, fate determination, differentiation and aging and senescence. They bind beta-catenin and can act as transcriptional activators or repressors for Wnt target genes, and have been shown to regulate specific target genes during CNS development downstream of Wnt signaling. TCF3/Lef complexes are also known to play key roles in controlling cell fate lineages in multipotent skin stem cells.

PAKs, p21 activated kinases, are a family of serine/threonine protein kinases comprised of six isoforms, PAK1-6, and they play important roles in cytoskeleton dynamics, cell survival and proliferation. Each of these isoforms contains a C-terminal catalytic domain and an N-terminal regulatory domain with a small G protein binding motif. OSR1, oxidative stress response 1, is activated only by osmotic stresses, like sorbital or NaCl. It has been predicted that OSR1 phosphorylates PAK1 in the regulatory domain at thr84 and inhibits activation of JNK and MAPK pathway. It has also been suggested that OSR1 may have a regulating function with actin cytoskeleton because it can phosphorylate PAK1 at thr84 and bind to gelsolin. PAK1 pT84 Antibody is ideal for researchers interested in cell cycle research.

C12orf23 (chromosome 12 open reading frame 23), also known as FLJ11721, FLJ13959 or MGC17943, is a 116 amino acid multi-pass membrane protein belonging to the UPF0444 family. C12orf23 is encoded by a gene located on human chromosome 12, which encodes over 1,100 genes and comprises approximately 4.5% of the human genome. Chromosome 12 is associated with a number of skeletal deformities, including hypochondrogenesis, achondrogenesis and Kniest dysplasia. Noonan syndrome, which includes heart and facial developmental defects among the primary symptoms, is caused by a mutant form of PTPN11 gene product, SH-PTP2. Chromosome 12 is also home to a homeobox gene cluster which encodes crucial transcription factors for morphogenesis, and the natural killer complex gene cluster encoding C-type lectin proteins which mediate the NK cell response to MHC I interaction. Trisomy 12p leads to facial development defects, seizure disorders and a host of other symptoms varying in severity depending on the extent of mosaicism and is most severe in cases of complete trisomy.

Polo-like kinases are a family of serine/threonine protein kinases, named after the prototypic founding member of the family, the polo gene product of Drosophila melanogaster. The polo kinase was originally identified in mutants that display abnormal mitotic spindle organization. Subsequently, potential homologues of Drosophila polo have been identified in yeasts (Cdc5p in Saccharomyces cerevisiae; plo1+ in Schizosaccharmoyces pombe) and in mammals (polo-like kinase 1; Plk1). Genetic and biochemical studies suggest that polo, Cdc5p and plo1+ may be required for mitotic spindle organization and, possibly, for cytokinesis. Likewise, the patterns of expression, activity and subcellular localization of Plk1 suggest that Plk12 may function during mitosis in spindle assembly and function. Recent studies have demonstrated that mammalian Plks regulate the function of the Golgi complex, a cellular organelle closely associated with the centrosome and also have microtubule organization activity. Furthermore, deregulated expression of human PLK1 and PLK3 is strongly correlated with the development of many types of malignancies, and ectopic expression of kinase-active Plk3 or Plk1 dominant negative protein leads to rapid cell death.

The RNAs that direct protein synthesis in animals and plant cells are synthesized in the nucleus as large precursors (pre-mRNAs). The protein coding sequences in pre-mRNA molecules are arranged in discontinuous segments - exons interspersed with noncoding sequences - introns. In a process termed splicing, these introns are efficiently removed before the pre-mRNA is transported from the nucleus to the cytoplasm, where it is translated into protein. Studies have shown that nuclear pre-mRNA splicing takes place in a multi-component structure termed a spliceosome. The polypyrimidine tract-binding (PTB) protein-associated splicing factor (PSF), which plays an essential role in mammalian spliceosomes, is a ubiquitous nuclear matrix protein. A complex between PTB and PSF is necessary for pre-mRNA splicing. PSF contains two consensus RNA-binding domains and an unusual amino terminus rich in proline and glutamine residues. The RNA-binding properties of PSF are apparently identical to those of PTB. Both proteins, together and independently, bind the polypyrimidine tract of mammalian introns. However, the nuclear localization of PSF and PTB and their distribution in subnuclear fractions differ markedly: isolated nuclear matrices contain a bulk of PSF, but only minor amounts of PTB. In confocal microscopy both proteins appear in speckles, the majority of which do not co-localize. These PTB/PSF complexes, as well as the observed PSF-PTB interaction, may reflect the presence of PTB and PSF in spliceosomal complexes during RNA processing, although other data point to different cellular distribution and nuclear matrix association of the majority of PSF and PTB. The cleavage of PSF during lysis of immature myeloid cells is accompanied by digestion of the PTB splicing regulator but not other proteins tested. In contrast, during apoptosis PTB is degraded while PSF remains intact. Proteolytic degradation of PSF specifically occurs in intact myeloid cells and this process is enhanced upon immature myeloid cell lysis; PSF is completely cleaved to a 47 kDa proteolytic cleavage product (p47), due to potent proteolytic activity found in these cells but rare in other cells and tissues. Furthermore, p47 is abundant in intact normal and tumor myeloid cells while in other cell types it is undetectable. The bone marrow 47 kDa protein is a fragment constituting the N-terminal, protease-resistant half of the splicing factor PSF. PSF is highly basic and migrates anomalously on SDS gels. The 47 kDa protein of mouse cells of immature myeloid origin (bone marrow and acute myeloid leukemia) exhibits a gel migration pattern corresponding to a 49 kDa molecule. In other cell types such as lymphoid cells and in peripheral blood cells, PSF appears as approx. 100 kDa or 75 kDa molecules. The sequence of a fragment of mouse PSF was found to be remarkably similar to that of human PSF ( > 98% homology). Also, the sequences of PSF and the human (h) 100 kDa DNA-pairing protein (hPOMp100) reveals identity. Homologous pairing is a fundamental biological reaction implicated in various cellular processes such as DNA recombination and repair, chromosome pairing, sister chromatid cohesion and chromosome condensation, gene inactivation and initiation of replication. The base pairing is also involved in spliceosome assembly resulting in formation of a dynamic Holliday-like structure within which splicing occurs. Indeed, PSF/hPOMp100 bind both singlestranded (ss) and double-stranded (ds) DNA and facilitates the renaturation of complementary ssDNA molecules. Importantly, PSF/hPOMp100 promotes the formation of D-loops in superhelical duplex DNA. PSF/hPOMp100 also serves as an efficient substrate for protein kinase C (PKC) in vitro. PKC phosphorylation of PSF/hPOMp100 stimulates its DNA binding and D-loop formation activity suggesting a possible regulatory mechanism. PSF has been demonstrated to interact with a variety of cellular targets including the human pro-oncoproteins EWS, hPOMp75/TLS and calmodulin, the RNA/DNAbinding nuclear protein p54nrb/NonO (the homolog of PSF) and DNA topoisomerase. A direct interaction has been observed, between PSF and topoisomerase I which has been implied in DNA recombination, DNA repair, and chromosome formation and may act as a transcription factor and a protein kinase. PSF is also expressed by differentiating neurons in developing mouse brain. Both the expression of PSF mRNA in cortex and cerebellum and PSF immunoreactivity in all brain areas has been found to be high during embryonic and early postnatal life. In adult tissue, only various neuronal populations in the hippocampus and olfactory bulb express PSF. PSF is expressed by differentiating neurons but not by astrocytic cells including radial glia; however oligodendrocytes differentiating in vitro were found to express it. The restricted expression of PSF suggests that it is involved in the control of neuronal-specific splicing events occurring at particular stages of neuronal differentiation and maturation. Monoclonal antibodies reacting specifically with PSF are useful tools for the molecular identification and characterization of the functional activity of PSF.
