Anti-Swip-1 antibodies enable researchers to detect and measure the Swip-1 antigen in biological samples. This target is a reported synonym of the WSB1 gene, which encodes WD repeat and SOCS box containing 1. This protein is known to function in intracellular signal transduction and protein ubiquitination, among other biological roles. The human version of Swip-1 has a canonical amino acid length of 421 residues and a protein mass of 47.4 kilodaltons, although 4 isoforms have been identified. It is reported to be notably expressed in many tissues, such as the appendix and colon.
