Product Specific Information
PA1-972 detects Proteasome 20S LMP7 in western blot and immunofluorescence.
PA1-972 can be used with blocking peptide PEP-132.
Target Information
The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure composed of four rings of 28 non-identical subunits: two rings of seven alpha subunits and two rings of seven beta subunits. Proteasomes are abundant throughout eukaryotic cells and cleave peptides in an ATP/ubiquitin-dependent, non-lysosomal pathway.
The immunoproteasome, a modified form, processes class I MHC peptides. The PSMB8 gene encodes a proteasome B-type (T1B family) 20S core beta subunit located in the MHC class II region. Expression is induced by gamma interferon, replacing the catalytic subunit 3 (proteasome beta 5 subunit) in the immunoproteasome. Proteolytic processing generates the mature subunit. Two transcript variants encode isoforms that yield the same mature protein.
