Syngap1 - synaptic Ras GTPase activating protein 1 Gene

Also Known as Syngap

Species: Rattus norvegicus

Gene Type: protein coding
Gene ID: 192117

Summary

This gene encodes a Ras GTPase activating protein that is a member of the N-methyl-D-aspartate receptor complex. The N-terminal domain of the protein contains a Ras-GAP domain, a pleckstrin homology domain, and a C2 domain that may be involved in binding of calcium and Phospholipids. The C-terminal domain consists of a ten histidine repeat region, serine and tyrosine phosphorylation sites, and a T/SXV motif required for postsynaptic scaffold protein interaction. The encoded protein negatively regulates Ras, Rap and alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor trafficking to the postsynaptic membrane to regulate synaptic plasticity and neuronal homeostasis. Homozygous null mutations in mice result in early post-embryonic lethality, while heterozygous mutant mice display a variety of phenotypes that include learning and memory defects, hyperactivity, and audiogenic seizures.
