Anti-skNAC antibodies enable researchers to detect and measure the skNAC antigen in biological samples. This target is a reported synonym of the NACA gene, which encodes nascent polypeptide associated complex subunit alpha. This protein is known to function in the regulation of transcription and protein transport, among other biological roles. The human version of skNAC has a canonical amino acid length of 215 residues and a protein mass of 23.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells. skNAC is a member of the NAC-alpha protein family.
