  • Primary antibody notesSynaptic Ras GTPase Activating Protein (SynGAP) is a PDZ-domain interacting protein expressed almost exclusively in the brain. SynGAP has been shown to be a major component of postsynaptic density and associates with post synaptic density 95 kDa (PSD-95), a synaptic scaffold protein, and synaptic N-methyl-D-aspartate (NMDA) receptors. SynGAP Ras-GTPase activity has also been shown to be inhibited by phosphorylation by CaM kinase II, another abundant protein located in the postsynaptic density. It has been proposed that SynGAP may function as a negative regulator of MAP Kinase activation in the absence of active NMDA receptors.

  • FunctionMajor 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. May be involved in certain forms of brain injury, leading to long-term learning and memory deficits.
  • Involvement in diseaseDefects in SYNGAP1 are the cause of mental retardation autosomal dominant type 5 (MRD5) [MIM:612621]. Mental retardation is characterized by significantly sub-average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period. MRD5 patients show global developmental delay with delayed motor development, hypotonia, moderate-to-severe mental retardation, and severe language impairment. Autism can be present in some patients.
  • Sequence similaritiesContains 1 C2 domain.
    Contains 1 PH domain.
    Contains 1 Ras-GAP domain.
  • Post-translational
    Phosphorylated by CaM-kinase II. Dephosphorylated upon NMDA receptor activation or SYNGAP1/MPDZ complex disruption.
