26S Proteasome p50 (112) AC

26S Proteasome p50 Antibody (112) is an IgG_2b mouse monoclonal 26S Proteasome p50 antibody (also designated 26S Proteasome p50 antibody) that detects the 26S Proteasome p50 protein of Drosophila melanogaster origin by WB and IP. 26S Proteasome p50 Antibody (112) is available as both the non-conjugated anti-26S Proteasome p50 antibody form, as well as multiple conjugated forms of anti-26S Proteasome p50 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor^® conjugates. The 26S proteasome is a large complex involved in the intracellular degradation of proteins in eukaryotes. Ubiquitination by E3 ubiquitin ligases targets proteins for degradation by this complex. The 26S proteasome plays an important role in the regulation of many biological processes. It is composed of over 30 different subunits and contains at least two copies of each subunit. Assembly of this large complex is ATP-dependent. Due to its size, it is fairly unstable and often disassociates into subcomplexes (including a 20S core and two 19S regulatory complexes). The 26S proteasome p50 (also known as Rpt5 in yeast and S6′ in human) is one of the six ATPase base subunits of the 19S regulatory complex. The 19S regulatory complex recognizes ubiquitinated proteins, removes the ubiquitin chains and translocates the proteins to the 20S core for degradation. The 26S proteasome p50 is a polyubiquitin interacting protein that plays a role in proteolytic signal recognition.
