PSMB8 antibody
Goat anti Human PSMB8 antibody recognizes proteasome subunit beta type-8, also known as Low molecular mass protein 7, macropain subunit C13, multicatalytic endopeptidase complex subunit C13, proteasome component C13, and proteasome subunit beta-5i.
The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure. The core structure 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. 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. PSMB8 encodes a member of the proteasome B-type family, also known as the T1B family, that is a 20S core beta subunit. PSMB8 is located in the class II region of the MHC (major histocompatibility complex). Expression of PSMB8 is induced by gamma interferon and PSMB8 product replaces catalytic subunit 3 (proteasome beta 5 subunit) in the immunoproteasome. Proteolytic processing is required to generate a mature subunit. Two alternative transcripts encoding two isoforms have been identified; both isoforms are processed to yield the same mature subunit (provided by RefSeq, Jul 2008).
Goat anti Human PSMB8 antibody detects a band of 23 kDa. The antibody has been extensively validated for western blotting using whole cell lysates.
