The proteasome (prosome, macropain) 26S subunit, ATPase, 4 ELISA kits listed below are analytical tools for measuring concentrations of proteasome (prosome, macropain) 26S subunit, ATPase, 4 in various samples. proteasome (prosome, macropain) 26S subunit, ATPase, 4 is an alternative name for the human PSMC4 gene, which encodes the protein, proteasome 26S subunit, ATPase 4. It has been mentioned that proteasome (prosome, macropain) 26S subunit, ATPase, 4 plays a role in proteolysis, among other functions. Structurally, the PSMC4 protein is 418 amino acid residues in length and 47.4 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. Other names for this target antigen include MIP224, RPT3, and S6.
