Genes affected

NCKAP1 (HGNC:7666): (NCK associated protein 1) Contributes to small GTPase binding activity. Involved in Rac protein signal transduction; positive regulation of Arp2/3 complex-mediated actin nucleation; and positive regulation of lamellipodium assembly. Located in extracellular exosome and focal adhesion. Part of SCAR complex. [provided by Alliance of Genome Resources, Apr 2022]
