== Disease ==
[https://www.uniprot.org/uniprot/SRGP2_HUMAN SRGP2_HUMAN] A chromosomal aberration disrupting SRGAP2 has been found in a patient with early infantile epileptic encephalopathy. Balanced translocation t(1;9)(q32;q13).
== Function ==
[https://www.uniprot.org/uniprot/SRGP2_HUMAN SRGP2_HUMAN] RAC1 GTPase activating protein (GAP) that binds and deforms membranes, and regulates actin dynamics to regulate cell migration and differentiation. Plays an important role in different aspects of neuronal morphogenesis and migration mainly during development of the cerebral cortex. This includes the biogenesis of neurites, where it is required for both axons and dendrites outgrowth, and the maturation of the dendritic spines. Also stimulates the branching of the leading process and negatively regulates neuron radial migration in the cerebral cortex. Its interaction and inhibition by SRGAP2C reduces the rate of spine maturation, alters dendritic spine morphology and density and indirectly increases neuronal migration. It may have implications for cognition, learning and memory. In non-neuronal cells, it may also play a role in cell migration by regulating the formation of lamellipodia and filopodia.<ref>PMID:20810653</ref> <ref>PMID:21148482</ref> <ref>PMID:22559944</ref>
