Anti-RCL1 antibodies are used in the immunodetection of the protein RNA terminal phosphate cyclase like 1. In humans, the canonical protein has a reported length of 373 amino acid residues and a mass of 40.8 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. A member of the RNA 3'-terminal cyclase protein family, RCL1 is known to be a part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. Synonyms for this target antigen include RPCL1, RNA 3'-terminal phosphate cyclase-like protein, RNA cyclase homolog, and RNAC. RCL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RCL1 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.
