BDNF belongs to the neurotrophin family and regulates the survival and differentiation of neurons during development. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. Microglia release BDNF that may contribute to neuroinflammation and neuropathic pain. FUNCTION: Promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. Major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. Post Translation Modification (PTM): The propeptide is N-glycosylated and glycosulfated. PTM: Converted into mature BDNF by plasmin (PLG) (By similarity). DISEASE: Defects in BDNF are a cause of congenital central hypoventilation syndrome (CCHS); also known as congenital failure of autonomic control or Ondine curse. CCHS is a rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia. CCHS is frequently complicated with neurocristopathies such as Hirschsprung disease that occurs in about 16% of CCHS cases. SIMILARITY: Belongs to the NGF-beta family.

Calcium/calmodulin-stimulated protein kinase II (CaMKII) is composed of four different chains (alpha, beta, gamma, and delta) and is abundantly expressed in neurons. CaMKII is involved in regulating many aspects of neuronal function, including neurotransmitter synthesis and release, modulation of ion channel activity and cellular transport. The enzymatic function of CaMKII is regulated by its multiple phosphorylation sites and targeting to sub-cellular locations through interactions with protein binding partners. Phosphorylation of Thr253 has been identified in vivo and found to alter the interaction of CaMKII with binding partners, but not change its enzymatic activity. Thus, phosphorylation of Thr253 is suggested to modulate functional responses based on its binding partner and subsequently its sub-cellular localization.

Required to maintain individual mitotic chromosomes dispersed in the cytoplasm following nuclear envelope disassembly (PubMed:27362226). Associates with the surface of the mitotic chromosome, the perichromosomal layer, and covers a substantial fraction of the chromosome surface (PubMed:27362226). Prevents chromosomes from collapsing into a single chromatin mass by forming a steric and electrostatic charge barrier: the protein has a high net electrical charge and acts as a surfactant, dispersing chromosomes and enabling independent chromosome motility (PubMed:27362226). Binds DNA, with a preference for supercoiled DNA and AT-rich DNA (PubMed:10878551). Does not contribute to the internal structure of mitotic chromosomes (By similarity). May play a role in chromatin organization (PubMed:24867636). It is however unclear whether it plays a direct role in chromatin organization or whether it is an indirect consequence of its function in maintaining mitotic chromosomes dispersed (Probable).

The green fluorescent protein (GFP) is a 27 kDa protein isolated originally from the jellyfish Aequoria victoria. It has an endogenous fluorochrome activity with excitation maximum at 395nm and emission maximum at 509 nm, which is similar to that of fluorescein. GFP can be expressed in fluorescent form in essentially any prokaryotic or eukaryotic cell.
This GFP rabbit antibody was made against a recombinant GFP construct originating from an Aequoria species which was engineered to improve spectral properties and prevent oligomerization (1). This form of GFP, referred to as AcGFP, is 94% identical to the eGFP developed by Tsien and co-workers. The antibody can be used to verify the expression, size and stability of both AcGFP and eGFP fusion proteins in western blotting experiments and to amplify GFP signals in tissues of transgenic animals.

The Lamin proteins are members of the intermediate filament protein family but are located inside the nucleus rather than in the cytoplasm (1). The lamins function as skeletal components tightly associated with the inner nuclear membrane. Originally the proteins of the nuclear cytoskeleton were named Lamin A, B and C, from top to bottom as visualized on SDS-PAGE gels. Subsequently it was found that Lamins A and C were coded for by a single gene (2), while the Lamin B band may contain two proteins encoded by two genes now called Lamin B1 and Lamin B2. Lamin A has a mass of about 74kDa while Lamin C is 65kDa. The Lamin A protein includes 98 amino acids missing from Lamin C, while Lamin C has a C-terminal 6 amino acid peptide not present in Lamin A. Apart from these regions Lamin A and C are identical so that antibodies raised against either protein are likely to cross react with the other, as is the case with this monoclonal. Lamin polymerization and depolymerization is regulated by phosphorylation by cyclin dependent protein kinase 1 (CDK1), the key component of "maturation promoting factor", the central regulator of cell division. Activity of this kinase increases during cell division and is responsible for the breakdown of the nuclear lamina. Mutations in the LMNA gene are associated with several serious human diseases, including Emery-Dreifuss muscular dystrophy, familial partial lipodystrophy, limb girdle muscular dystrophy, dilated cardiomyopathy, Charcot-Marie-Tooth disease type 2B1, and Hutchinson-Gilford progeria syndrome. This family of diseases belong to a larger group which are often referred to as Laminopathies, though some laminopathies are associated in defects in Lamin B1, B2 or one or other of the numerous nuclear lamina binding proteins. A truncated version of lamin A, commonly known as progerin, causes Hutchinson-Gilford progeria syndrome, a form of premature aging (3).

SOD3 is a member of the superoxide dismutase protein family. SODs are antioxidant enzymes that catalyse the dismutation of two superoxide radicals into hydrogen peroxide and oxygen. SOD3 is thought to protect the brain, lungs and other tissues from oxidative stress. It is secreted into the extracellular space and forms a glycosylated homotetramer that is anchored to the extracellular matrix and cell surfaces through an interaction with heparan sulfate proteoglycan and collagen. A small percentage of SOD3 is cleaved near the C-terminus before secretion to generate circulating tetramers that do not interact with the extracellular matrix.

Saporin is a ribosome-inactivating protein (RIP) of type I. This monomeric RNA N-glycosidase purified from seeds of the plant Saponaria officinalis also known as Soapwort, is capable of specific depurination of eukaryotic ribosomes thus arresting protein synthesis. No ligand has been identified in saporin hence its inability to transverse the cell membrane. Due to its toxicity and stability of the structure, saporin has proven extremely useful for construction of immunotoxins.
