Anti-KAP24.1 antibodies enable researchers to detect and measure the KAP24.1 antigen in biological samples. This target is a reported synonym of the KRTAP24-1 gene, which encodes keratin associated protein 24-1. The human version of KAP24.1 has a canonical amino acid length of 254 residues and a protein mass of 27.7 kilodaltons. It is reported to be notably expressed in the hair and testis. KAP24.1 is a member of the PMG protein family.
