Anti-pof14 antibodies enable researchers to detect and measure the pof14 antigen in biological samples. This target is a reported synonym of the GDF9 gene, which encodes growth differentiation factor 9. This protein is known to function in the regulation of cell growth and the regulation of cell proliferation, among other biological roles. The human version of pof14 has a canonical amino acid length of 454 residues and a protein mass of 51.4 kilodaltons. It is reported to be a secreted protein that is notably expressed in the testis. pof14 is a member of the TGF-beta protein family.
