Anti-STNB1 antibodies enable researchers to detect and measure the STNB1 antigen in biological samples. This target is a reported synonym of the STON1 gene, which encodes stonin 1. This protein is suspected to be involved in the endocytic machinery. The human version of STNB1 has a canonical amino acid length of 735 residues and a protein mass of 83.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include SALF, SBLF, and STN1.
