WASP a member of the Wiskott-Aldrich syndrome (WAS) family of proteins. A cytoplasmic protein expressed exclusively in hematopoietic cells. Transduces signals from surface receptors to the actin cytoskeleton. Associates with the small GTPase, Cdc42, known to regulate formation of actin filaments, and the cytoskeletal organizing complex, Arp2/3. Mutated in Wiskott-Aldrich syndrome, a rare, inherited, X-linked, recessive disease characterized by immune dysregulation and microthrombocytopenia.
