Summaries for GPHN Gene

Entrez Gene Summary for GPHN Gene

  • This gene encodes a neuronal assembly protein that anchors inhibitory neurotransmitter receptors to the postsynaptic cytoskeleton via high affinity binding to a receptor subunit domain and tubulin dimers. In nonneuronal tissues, the encoded protein is also required for molybdenum cofactor biosynthesis. Mutations in this gene may be associated with the neurological condition hyperplexia and also lead to molybdenum cofactor deficiency. Numerous alternatively spliced transcript variants encoding different isoforms have been described; however, the full-length nature of all transcript variants is not currently known.

GeneCards Summary for GPHN Gene

GPHN (Gephyrin) is a Protein Coding gene. Diseases associated with GPHN include molybdenum cofactor deficiency c and retinopathy pigmentary mental retardation. Among its related pathways are Disease and Metabolism. GO annotations related to this gene include transferase activity.

UniProtKB/Swiss-Prot for GPHN Gene

  • Microtubule-associated protein involved in membrane protein-cytoskeleton interactions. It is thought to anchor the inhibitory glycine receptor (GLYR) to subsynaptic microtubules (By similarity). 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.
