Anti-GABAB Receptor (Ser923), R1-Subunit Antibody

Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system. There are two major classes of GABA receptors: the GABA-A and the GABA-B subtype of receptors. GABA-B receptors are heterodimeric G protein-coupled receptors that mediate slow synaptic inhibition in the central nervous system. Phosphorylation enhances GABA-B receptor effector coupling (Couve et al., 2004). Phosphorylation of Ser-923 is thought to be important in the regulation of GABA-B receptor function.
