Anti-Sgn1 antibodies enable researchers to detect and measure the Sgn1 antigen in biological samples. This target is a reported synonym of the GPS1 gene, which encodes G protein pathway suppressor 1. This protein is an important component of the COP9 signalosome complex (CSN), a complex involved in various cellular and developmental processes. The human version of Sgn1 has a canonical amino acid length of 491 residues and a protein mass of 55.5 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells. Other names for this target antigen include COPS1 and CSN1. Indicated applications for Sgn1 antibodies listed below include ELISA and Western Blot.
