Gephyrin Antibody

In neuronal tissue, gephyrin is a scaffolding protein that self assembles in a complex, flat submembraneous lattice that inhibits mobility of the glycine receptors (GlyR) and GABA-A receptors (GABA-A-R) causing clustering at post synaptic sites (Groeneweg et al, 2018) . In non-neuronal tissue gephyrin plays a critical role in the molybdendum cofactor (MoCo) biosynthesis of essential life molybdoenzymes, like sulphite oxidase (Groeneweg et al, 2018) . Three functional domains have been identified in gephyrin: the stable, structural G and E domains, and the C domain which is intrinsically unstructured leading to multiple isoforms (108, 105, 102, 98, 90 kDa) (Kawasaki, et al 1997) . The 93 kDa protein predominantly expressed in the brain and located in the plasma membrane, has a 10X stronger affinity for the GlyR than the GABA-A-R. Gephyrin’s flexibility to change its size and molecular density is directly correlated to its high affinity to the GlyR-β subunit, and is required for anchoring and accurate clustering of GlyRs at post synaptic sites and microtubule transport chains (Greoneweg et al, 2018) . A consistent parameter in the pathogenesis of Alzheimers Disease shows a decrease of inhibitory GABAergic synapses and gephyrin, and increased levels of an insoluble 37 kDa gephyrin fragment not detected in healthy, non-AD models (Kiss et al, 2016) .
