Anti-PN8 antibodies enable researchers to detect and measure the PN8 antigen in biological samples. This target is a reported synonym of the NANOGP8 gene, which encodes Nanog homeobox retrogene P8. This protein is known to function in the regulation of cell proliferation and the regulation of transcription, among other biological roles. The human version of PN8 has a canonical amino acid length of 305 residues and a protein mass of 34.7 kilodaltons. It is reported to be localized in the nucleus of cells. PN8 is a member of the Nanog homeobox protein family.
