Anti-BCA2 antibodies enable researchers to detect and measure the BCA2 antigen in biological samples. This target is a reported synonym of the RNF115 gene, which encodes ring finger protein 115. This protein is known to function in protein ubiquitination, among other biological roles. The human version of BCA2 has a canonical amino acid length of 304 residues and a protein mass of 33.7 kilodaltons. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types.
