Anti-UTP14C small subunit processome component antibodies are used for the immunodetection of the protein encoded by the UTP14C gene. In humans, the canonical protein has a reported length of 766 amino acid residues and a mass of 87.2 kDa. Its subcellular localization is in the nucleus. It is notably expressed in the testis. A member of the UTP14 protein family, it is known to be important for spermatogenesis. Other names for this target antigen include KIAA0266, UTP14B, U3 small nucleolar RNA-associated protein 14 homolog C, UTP14, U3 small nucleolar ribonucleoprotein, homolog C, UTP14, small subunit processome component homolog C, and 2700066J21Rik. Gene orthologs have been identified in the mouse and chimpanzee species.
