Anti-Human mGlyR/GPR158 Recombinant Nanobody |抗人mGlyR/GPR158纳米抗体(靶标：人G蛋白偶联受体158/mGlyR)

Metabotropic glycine receptor (mGlyR/GPR158) is a ~135 kDa protein. Metabotropic receptor for glycine that controls synapse formation and function in the brain. Acts as an atypical G-protein coupled receptor that recruits and regulates the RGS7-GNB5 complex instead of activating G proteins. In absence of glycine ligand, promotes the GTPase activator activity of RGS7, increasing the GTPase activity of G protein alpha subunits, thereby driving them into their inactive GDP-bound form. Glycine-binding changes the conformation of the intracellular surface, inhibiting the GTPase activator activity of the RGS7-GNB5 complex, promoting G protein alpha subunits into their active GTP-bound form and regulating cAMP levels. Also able to bind taurine, a compound closely related to glycine, but with a two-fold lower affinity.
