CC -!- FUNCTION: RAC1 GTPase activating protein (GAP) that binds and CC deforms membranes, and regulates actin dynamics to regulate cell CC migration and differentiation. Plays an important role in CC different aspects of neuronal morphogenesis and migration mainly CC during development of the cerebral cortex. This includes the CC biogenesis of neurites, where it is required for both axons and CC dendrites outgrowth, and the maturation of the dendritic spines. CC Also stimulates the branching of the leading process and CC negatively regulates neuron radial migration in the cerebral CC cortex. Its interaction and inhibition by SRGAP2C reduces the rate CC of spine maturation, alters dendritic spine morphology and density CC and indirectly increases neuronal migration. It may have CC implications for cognition, learning and memory. In non-neuronal CC cells, it may also play a role in cell migration by regulating the CC formation of lamellipodia and filopodia. CC -!- SUBUNIT: Homodimer (Probable). Forms heterooligomer with SRGAP1 CC and SRGAP3 through its F-BAR domain. Interacts (via SH3 domain) CC with GPHN (By similarity). Interacts with SRGAP2C; formation of CC the heterodimer alters SRGAP2 function. Interacts (via SH3 domain) CC with FMNL1 (activated by RAC1); regulates the actin filament CC severing activity of FMNL1 and actin dynamics. Interacts (via SH3 CC domain) with FMNL3. Interacts with RAC1; specifically stimulates CC RAC1 GTPase activity. Probably interacts with ROBO1 and ROBO2. CC Interacts with FASLG. Interacts with PRMT5. CC -!- INTERACTION: CC O95466:FMNL1; NbExp=3; IntAct=EBI-1051034, EBI-720020; CC O14744:PRMT5; NbExp=4; IntAct=EBI-1051034, EBI-351098; CC -!- SUBCELLULAR LOCATION: Cell membrane. Cell projection, dendritic CC spine. Cell junction, synapse, postsynaptic cell membrane, CC postsynaptic density (By similarity). Cell junction, synapse, CC postsynaptic cell membrane (By similarity). Cell projection, CC lamellipodium. Cytoplasmic vesicle, phagosome (By similarity). CC Nucleus (By similarity). Cytoplasm (By similarity). Note=Recruited CC to actin-rich phagosomes during phagocytosis (By similarity). CC Translocates from nucleus to cytoplasm during development (By CC similarity). CC -!- DOMAIN: The F-BAR domain mediates oligomerization, binds CC membranes, and induces plasma membrane protrusions. CC -!- PTM: Methylation at Arg-927 is required for the stimulation of CC cell migration, dimerization and localization at the plasma CC membrane protrusions. CC -!- DISEASE: Note=A chromosomal aberration disrupting SRGAP2 has been CC found in a patient with early infantile epileptic encephalopathy. CC Balanced translocation t(1;9)(q32;q13). CC -!- MISCELLANEOUS: There are 3 duplications of SRGAP2 in the human CC genome as a result of segmental gene duplications. SRGAP2C is the CC only one to be fixed at a diploid state in the human genome. CC Moreover, SRGAP2C is functional, interacts with and inhibits CC SRGAP2 and is human-specific. The appearance of SRGAP2C in the CC human genome is estimated to 2,4 million years ago, which CC corresponds to the beginning of neocortex expansion in human CC evolution and it may have played an important role in this process CC through its interaction with SRGAP2 function. CC -!- SIMILARITY: Contains 1 FCH domain. CC -!- SIMILARITY: Contains 1 Rho-GAP domain. CC -!- SIMILARITY: Contains 1 SH3 domain.
