CC   -!- FUNCTION: Major constituent of the PSD essential for postsynaptic
CC       signaling. Inhibitory regulator of the Ras-cAMP pathway. Member of the
CC       NMDAR signaling complex in excitatory synapses, it may play a role in
CC       NMDAR-dependent control of AMPAR potentiation, AMPAR membrane
CC       trafficking and synaptic plasticity. Regulates AMPAR-mediated miniature
CC       excitatory postsynaptic currents. Exhibits dual GTPase-activating
CC       specificity for Ras and Rap. May be involved in certain forms of brain
CC       injury, leading to long-term learning and memory deficits (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts KLHL17, CAMK2A and CAMK2B (By similarity). Interacts
CC       with MPDZ. {ECO:0000250, ECO:0000269|PubMed:15312654}.

CC   -!- DISEASE: Intellectual developmental disorder, autosomal dominant 5
CC       (MRD5) [MIM:612621]: A disorder characterized by significantly below

CC       adaptive behavior and manifested during the developmental period. MRD5
CC       patients show global developmental delay with delayed motor
CC       development, hypotonia, moderate-to-severe intellectual disability, and
CC       severe language impairment. Epilepsy and autism can be present in some
CC       patients. {ECO:0000269|PubMed:19196676, ECO:0000269|PubMed:21076407,
