Anti-SNRNP31 antibodies are protein reagents that detect specific antigens. The SNRNP31 antigen is another term for the human protein zinc finger CCHC-type and RNA binding motif containing 1, encoded by the ZCRB1 gene. The protein is known to function in RNA splicing, among other biological roles. Canonically, it has an amino acid length of 217 residues and a mass of 24.6 kilodaltons. Its subcellular localization is in the nucleus.
