Anti-BIA2 antibodies enable researchers to detect and measure the BIA2 antigen in biological samples. This target is a reported synonym of the TRIM58 gene, which encodes tripartite motif containing 58. This protein is known to function in innate immune responses and autophagy pathways, among other biological roles. The human version of BIA2 has a canonical amino acid length of 486 residues and a protein mass of 54.8 kilodaltons. BIA2 is a member of the TRIM/RBCC protein family.
