The following Ribonuclease L ELISA kits are useful research tools for the measurement of ribonuclease L in biological samples. In humans this protein is encoded by the RNASEL gene. This protein is a reported endoribonuclease that functions in the interferon (IFN) antiviral response. The canonical protein structure is reported to have an amino acid length of 741 residues, a mass of 83.5 kDa, and is a member of the Protein kinase protein superfamily. Its subcellular location is known to be in the mitochondria and cytoplasm. In addition, it is reported to be highly expressed in spleen and thymus followed by prostate, testis, uterus, small intestine, colon and peripheral blood leukocytes. As many as 2 protein isoforms have been reported. The gene encoding this protein has been associated with the disease, Prostate cancer. This protein may also be known as RNS4, 2-5A-dependent ribonuclease, 2',5'-oligoisoadenylate synthetase-dependent, 2-5A-dependent RNase, interferon-induced 2-5A-dependent RNase, and PRCA1.
