Anti-KAT1 antibodies enable researchers to detect and measure the KAT1 antigen in biological samples. This target is a reported synonym of the HAT1 gene, which encodes histone acetyltransferase 1. This protein is reported to be a histone acetyltransferase that plays a role in different biological processes including cell cycle progression, glucose metabolism, histone production or DNA damage repair. The human version of KAT1 has a canonical amino acid length of 419 residues and a protein mass of 49.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus, mitochondria, and cytoplasm of cells and widely expressed in many tissue types. KAT1 is a member of the HAT1 protein family.
