Anti-HCSA antibodies enable researchers to detect and measure the HCSA antigen in biological samples. This target is a reported synonym of the IGHMBP2 gene, which encodes immunoglobulin mu DNA binding protein 2. The human version of HCSA has a canonical amino acid length of 993 residues and a protein mass of 109.1 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. HCSA is a member of the DNA2/NAM7 helicase protein family.
