PSMC3 Antibody

PSMC3 is a subunit of the 26S proteasome. 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 which have a 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

For short periods of storage (days) store at 4˚ C. For longer periods of storage, store PSMC3 antibody at -20˚ C. As with any antibody avoid repeat freeze-thaw cycles.

PSMC3 antibody can be used for detection of PSMC3 by ELISA at 1:312500. PSMC3 antibody can be used for detection of PSMC3 by western blot at 1.25 μ g/mL, and HRP conjugated secondary antibody should be diluted 1:50,000 - 100,000.
