Anti-WASHC2A antibodies are used in the immunodetection of the protein WASH complex subunit 2A. In humans, the canonical protein has a reported length of 1341 amino acid residues and a mass of 147.2 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the FAM21 protein family, WASHC2A is known to act at least in part as component of the WASH core complex whose assembly at the surface of endosomes inhibits WASH nucleation-promoting factor (NPF) activity in recruiting and activating the Arp2/3 complex to induce actin polymerization and is involved in the fission of tubules that serve as transport intermediates during endosome sorting. Synonyms for this target antigen include WASH complex subunit FAM21B, alternative protein FAM21B, family with sequence similarity 21 member A, family with sequence similarity 21, member B, and WASH complex subunit FAM21A. Immunohistochemistry is the most common application for the WASHC2A antibodies listed below. Western Blot and Immunocytochemistry are also common applications.
