These P112 ELISA kits are immunodetection tools for measuring the levels of P112 in biological samples. P112 is an alias of the human PSMD1 gene, which encodes the protein, proteasome 26S subunit, non-ATPase 1. The protein is a known component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. The PSMD1 protein is 953 amino acid residues in length and 105.8 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. Other names for this target antigen include Rpn2.
