26S protease regulatory subunit S10B, also known as 26S proteasome AAA-ATPase subunit Rpt4, is an enzyme that in humans is encoded by the PSMC6gene.[5][6][7] This protein is one of the 19 essential subunits of a complete assembled 19S proteasome complex[8] Six 26S proteasome AAA-ATPase subunits (Rpt1, Rpt2, Rpt3, Rpt4 (this protein), Rpt5, and Rpt6) together with four non-ATPase subunits (Rpn1, Rpn2, Rpn10, and Rpn13) form the base sub complex of 19S regulatory particle for proteasome complex.[8]
