Predicted to enable SH3 domain binding activity and protein kinase A binding activity. Predicted to be involved in negative regulation of stress fiber assembly; positive regulation of lamellipodium assembly; and postsynaptic actin cytoskeleton organization. Predicted to act upstream of or within several processes, including Rac protein signal transduction; lamellipodium organization; and megakaryocyte development. Predicted to be located in several cellular components, including early endosome; lamellipodium; and ruffle. Predicted to be part of SCAR complex. Predicted to be active in synapse. Orthologous to human WASF2 (WASP family member 2). [provided by Alliance of Genome Resources, Apr 2022]
