Anti-C15orf43 antibodies enable researchers to detect and measure the C15orf43 antigen in biological samples. This target is a reported synonym of the TERB2 gene, which encodes telomere repeat binding bouquet formation protein 2. This protein is known to function in spermatogenesis, among other biological roles. The human version of C15orf43 has a canonical amino acid length of 220 residues and a protein mass of 25.3 kilodaltons. It is reported to be localized in the nucleus and chromosomes of cells. C15orf43 is a member of the TERB2 protein family.
