Anti-WASH1 antibody, Mouse monoclonal

Monoclonal Anti-WASH1 (mouse IgG1 isotype) is derived from the hybridoma WASH1-27 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with a synthetic peptide corresponding to an internal region of human WASH1. WASH1 (Wiskott-Aldrich Syndrome Protein and SCAR Homolog), a new member of the Wiskott−Aldrich Syndrome protein (WASP) family. Similar to other WASP family members, it contains a C-terminal for ′WH2, connecting and acidic′ (WCA) domain that binds to actin and the Arp2/3 complex. In addition, WASH1 also contains a short proline-rich region, a unique N-terminal domain termed WASH-homology domain (WAHD1), and a tubulin-binding region. Through its WAHD1 region, it interacts with family with sequence similarity 21 (FAM21), a protein that links WASH1 to endosomes. WASH1 forms part of a multiprotein complex composed of FAM21, KIAA1033 strumpellin and WASH-interacting protein (SWIP) and coiled coil domain containing 53 (CCDC53).

a synthetic peptide corresponding to an internal region of human WASH1 (GeneID: 100287171), conjugated to KLH. The corresponding sequence differs by one amino acid in mouse and rat.

Monoclonal Anti-WASH1 antibody produced in mouse has been used in may be used in various immunochemical techniques including immunoblotting (~72 kDa), immunoprecipitation and immunofluorescence.

WASH1 (Wiskott-Aldrich Syndrome Protein and SCAR Homolog), is a nucleation-promoting factor at the surface of endosomes. It recruits and activates the Arp2/3 complex to induce actin polymerization, playing a key role in the fission of endosomes. It associates with tubulin and localizes to early and recycling endosomes, where together with the Arp2/3 complex and actin, it is required for maintaining the shape of the endosomal compartment and the regulation of the retrograde transport.
