Anti-RPT2 antibodies enable researchers to detect and measure the RPT2 antigen in biological samples. This target is a reported synonym of the PSMC1 gene, which encodes proteasome 26S subunit, ATPase 1. This protein is a known component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. The human version of RPT2 has a canonical amino acid length of 440 residues and a protein mass of 49.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. RPT2 is a member of the AAA ATPase protein family.
