Supplier: Bioss

Members of the protein-tyrosine phosphatase superfamilycooperate with protein kinases to regulate cell proliferation anddifferentiation. This superfamily is separated into two familiesbased on the substrate that is dephosphorylated. One family, thedual specificity phosphatases (DSPs) acts on both phosphotyrosineand phosphoserine/threonine residues. This gene encodes differentbut related DSP proteins through the use of non-overlapping openreading frames, alternate splicing, and presumed differenttranscription promoters. Expression of the distinct proteins fromthis gene has been found to be tissue specific and the proteins maybe involved in postnatal development of specific tissues. A proteinencoded by the upstream ORF was found in skeletal muscle, whereasthe encoded protein from the downstream ORF was found only intestis. In mouse, a similar pattern of expression was found.Multiple alternatively spliced transcript variants were described,but the full-length sequence of only some were determined.[provided by RefSeq, Jul 2008].

Alpha-synuclein, a member of the synuclein family, is a protein that was first identified in 1988 whose name is derived from its localisation to both the synapse and nucleus (1-3). Specifically, it is expressed primarily in the brain, including Lewy Bodies (1-6). Alpha-synuclein is encoded by the SNCA gene, located on chromosome 4p21, and is processed as a 140 amino acid (aa) protein with a theoretical molecular weight of 14 kDa (1,2,4).

Supplier: ProSci Inc.

Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system, causing a hyperpolarization of the membrane through the opening of a Cl− channel associated with the GABAA receptor (GABAA-R) subtype. GABA plasma membrane transporters (GATs) influence synaptic neurotransmission by high-affinity uptake and release of GABA. To date, four distinct GABA transporters have been identified: GAT-1, GAT-2, GAT-3, and BGT-1. GAT-2 is found in a wide range of neuronal and non-neuronal cells including dendrites and axon terminals as well as epithelial cells and cells forming the pia and arachnoid complex (Conti et al., 1999).
