Anti-nuclear transcription factor Y, beta antibodies enable researchers to detect and measure the nuclear transcription factor Y, beta antigen in biological samples. This target is a reported synonym of the NFYB gene, which encodes nuclear transcription factor Y subunit beta. This protein is known to function in the regulation of transcription, among other biological roles. The human version of nuclear transcription factor Y, beta has a canonical amino acid length of 207 residues and a protein mass of 22.8 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include CBF-A, CBF-B, and HAP3.
