Description
Product Characteristics: LMP2 is a catalytic subunit of the 20S proteasome and, upon interferon gamma-induction, replaces the delta subunit. LMP2 alters the specificity of the 20S proteasome and is critical for the production of MHC class I ligands, production of T-lymphocytes, and is suggested to increase the efficiency of antigen presentation of the immune response.
Target Information: 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. This gene encodes a member of the peptidase T1A family, that is a 20S core alpha subunit. Multiple alternatively spliced transcript variants encoding two distinct isoforms have been found for this gene. [provided by RefSeq, Dec 2010]
