These RPN3 ELISA kits are immunodetection tools for measuring the levels of RPN3 in biological samples. RPN3 is an alias of the human PSMD3 gene, which encodes the protein, proteasome 26S subunit, non-ATPase 3. The protein is a known component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. The PSMD3 protein is 534 amino acid residues in length and 61 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. Other names for this target antigen include P58 and S3.
