Summaries for SYNGAP1 Gene

Entrez Gene Summary for SYNGAP1 Gene

  • The protein encoded by this gene is a major component of the postsynaptic density (PSD), a group of proteins found associated with NMDA receptors at synapses. The encoded protein is phosphorylated by calmodulin-dependent protein kinase II and dephosphorylated by NMDA receptor activation. Defects in this gene are a cause of mental retardation autosomal dominant type 5 (MRD5). [provided by RefSeq, Dec 2009]

GeneCards Summary for SYNGAP1 Gene

SYNGAP1 (Synaptic Ras GTPase Activating Protein 1) is a Protein Coding gene. Diseases associated with SYNGAP1 include Autosomal Dominant Non-Syndromic Intellectual Disability and Intellectual Disability. Among its related pathways are Interleukin-3, 5 and GM-CSF signaling and Signaling by GPCR. GO annotations related to this gene include GTPase activator activity and SH3 domain binding. An important paralog of this gene is RASAL2.

UniProtKB/Swiss-Prot for SYNGAP1 Gene

  • Major constituent of the PSD essential for postsynaptic signaling. Inhibitory regulator of the Ras-cAMP pathway. Member of the NMDAR signaling complex in excitatory synapses, it may play a role in NMDAR-dependent control of AMPAR potentiation, AMPAR membrane trafficking and synaptic plasticity. Regulates AMPAR-mediated miniature excitatory postsynaptic currents. Exhibits dual GTPase-activating specificity for Ras and Rap. May be involved in certain forms of brain injury, leading to long-term learning and memory deficits (By similarity).
