DESCRIPTION

Also known as GEPH_HUMAN, GPHN, GPH, KIAA1385. Microtubule-associated protein involved in membrane protein-cytoskeleton interactions. It is thought to anchor the inhibitory glycine receptor (GLYR) to subsynaptic microtubules (By similarity). Acts as a major instructive molecule at inhibitory synapses, where it also clusters GABA type A receptors (PubMed:25025157, PubMed:26613940)., Has also a catalytic activity and catalyzes two steps in the biosynthesis of the molybdenum cofactor. In the first step, molybdopterin is adenylated. Subsequently, molybdate is inserted into adenylated molybdopterin and AMP is released. Homotrimer, homodimer and homooligomer (PubMed:26613940). Interacts with GABARAP (By similarity). Interacts with SRGAP2 (via SH3 domain) (By similarity). Interacts with GABRA3 (PubMed:26613940). Interacts with GLRB (PubMed:26613940, PubMed:12684523). GABRA3 and GLRB occupy overlapping binding sites (By similarity). Interacts with ARHGAP32; IQSEC3, INSYN1 and INSYN2A (By similarity).
