>TIGR01242 26Sp45 26S proteasome subunit P45 family; InterPro: IPR005937 Intracellular proteins, including short-lived proteins such as cyclin, Mos, Myc, p53, NF-kappaB, and IkappaB, are degraded by the ubiquitin-proteasome system. The 26S proteasome (a 2 MDa complex) is made up of two subcomplexes: the 20S proteasome and the regulatory complex. The former is a 700 kDa cylindrical protease complex consisting of four stacks of heptameric rings with 28 subunits (i.e., 7777) with molecular masses of about 20-35 kDa, whereas the latter is a 700-1000 kDa complex consisting of at least 18 subunits with molecular masses of 28-110 kDa, including 6 putative ATPases (Rpt1-Rpt6) and 12 non-ATPase subunits (Rpn1-12). Members of the 26S proteasome subunit P45 family: ATPase p45/Sug1/Rpt6 may be phosphorylated within the proteasome. This phosphorylation event may play a key role in ATP-dependent proteolysis because a good correlation exists between the inhibition pattern of protein kinase inhibitors against the phosphorylation of p45 and that against the ATP-dependent proteolytic activity , . More information about these protein can be found at Protein of the Month: AAA ATPases .; GO: 0016787 hydrolase activity, 0030163 protein catabolic process, 0005634 nucleus, 0005737 cytoplasm.
