Anti-PSME3 Rabbit Polyclonal Antibody

Description: The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. 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. The immunoproteasome contains an alternate regulator, referred to as the 11S regulator or PA28, that replaces the 19S regulator. Three subunits (alpha, beta and gamma) of the 11S regulator have been identified. PSME3 is the gamma subunit of the 11S regulator. Six gamma subunits combine to form a homohexameric ring.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.

Two transcript variants encoding different isoforms have been identified.

Anti-Cop9 Signalosome Csn6 Subunit Rabbit Polyclonal Antibody

Description: The polyclonal antibody to Csn6 was generated by immunisation of rabbits with a synthetic peptide corresponding to residues [283-297] of the human Csn6 sequence. The antibody has been characterised by one-dimensional Western blotting. Vial contains a partially purified immunoglobulin preparation suspended phosphate-buffered saline containing 0.01M sodium azide. The COP9 signalosome, once defined as a repressor complex of light activated development in Arabidopsis, has recently been found in humans and is probably present in most multicellular organisms. The COP9 signalosome is closely related to the lid sub-complex of the 26S proteasome in structural composition and probably shares a common evolutionary ancestor. A multifaceted role of the COP9 signalosome in cell-signalling processes is hinted at by its associated novel kinase activity, as well as the involvement of its subunits in regulating multiple cell-signalling pathways and cell-cycle progression. The molecular genetic studies in Arabidopsis suggest that the complex functions as part of a highly conserved regulatory network, whose physiological rüle in animals has yet to be determined. The COP9 signalosome, also known as the the COP9 complex and JAB1-containing signalosome, is a conserved nuclear protein complex found in plants and animals. It is composed of eight distinct subunits, designated S1 to S8 (very recently re-designated Csn1-Csn8) according to the molecular weight of the mammalian complex subunits. Subunit composition and the subunit sequences are substantially conserved between the mammalian and the plant complexes, implying that the complex has a conserved cellular function in higher eukaryotic organisms. The role and function of Csn6 has yet to be determined although this subunit is known to interact with subunits Csn2 and Csn7 within the COP9 signalosome.
