Predicted to enable small GTPase binding activity. Predicted to be involved in several processes, including activation of cysteine-type endopeptidase activity; dendrite extension; and positive regulation of neurotrophin TRK receptor signaling pathway. Predicted to be located in perinuclear region of cytoplasm. Predicted to be part of SCAR complex. Predicted to be active in synapse. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 65. Orthologous to human CYFIP2 (cytoplasmic FMR1 interacting protein 2).
