Anti-Ribonuclease H2, subunit B antibodies enable researchers to detect and measure the Ribonuclease H2, subunit B antigen in biological samples. This target is a reported synonym of the RNASEH2B gene, which encodes ribonuclease H2 subunit B. This protein is known to function in in utero embryonic development and the regulation of gene expression, among other biological roles. The human version of Ribonuclease H2, subunit B has a canonical amino acid length of 312 residues and a protein mass of 35.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Ribonuclease H2, subunit B is a member of the RNase H2 subunit B protein family.
