IgG2b Description: Homo sapiens proteasome (prosome macropain) 26S subunit ATPase 3 (PSMC3)

WB 1:2000 IHC 1:50 IF 1:100 The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base which contains 6 ATPase subunits and 2 non-ATPase subunits and a lid which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome the immunoproteasome is the processing of class I MHC peptides. This gene encodes one of the ATPase subunits a member of the triple-A family of ATPases that have chaperone-like activity. This subunit may compete with PSMC2 for binding to the HIV tat protein to regulate the interaction between the viral protein and the transcription complex. A pseudogene has been identified on chromosome 9.
