The function of WASH6P (WASP family homolog 6, pseudogene, Ensembl gene identifier ENSG00000182484) is as follows. May act as a nucleation-promoting factor at the surface of endosomes, where it recruits and activates the Arp2/3 complex to induce actin polymerization, playing a key role in the fission of tubules that serve as transport intermediates during endosome sorting. .
