Anti-nuclear protein, co-activator of histone transcription antibodies enable researchers to detect and measure the nuclear protein, co-activator of histone transcription antigen in biological samples. This target is a reported synonym of the NPAT gene, which encodes nuclear protein, coactivator of histone transcription. This protein is known to function in in utero embryonic development and the regulation of transcription, among other biological roles. The human version of nuclear protein, co-activator of histone transcription has a canonical amino acid length of 1427 residues and a protein mass of 154.3 kilodaltons. It is reported to be localized in the nucleus of cells. nuclear protein, co-activator of histone transcription is a member of the NPAT protein family.
