Anti-CLP1 antibodies are used in the immunodetection of the protein cleavage factor polyribonucleotide kinase subunit 1. In humans, the canonical protein has a reported length of 425 amino acid residues and a mass of 47.6 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Clp1 protein family, CLP1 is reported to be a polynucleotide kinase that can phosphorylate the 5'-hydroxyl groups of double-stranded RNA (dsRNA), single-stranded RNA (ssRNA), double-stranded DNA (dsDNA) and double-stranded DNA:RNA hybrids. Synonyms for this target antigen include hClp1, polyribonucleotide 5'-hydroxyl-kinase Clp1, ATP/GTP-binding protein, cleavage and polyadenylation factor I subunit 1, and HEAB. CLP1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CLP1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
