Anti-WSB1 antibodies are used in the immunodetection of the protein WD repeat and SOCS box containing 1. In humans, the canonical protein has a reported length of 421 amino acid residues and a mass of 47.4 kDa. Up to 4 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the appendix and colon. WSB1 is a suspected substrate-recognition component of a SCF-like ECS (Elongin-Cullin-SOCS-box protein) E3 ubiquitin ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Synonyms for this target antigen include WD repeat and SOCS box-containing protein 1, SOCS box-containing WD protein SWiP-1, and SWIP1. WSB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of WSB1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
