This entry represents regulatory subunit 10B (gene name PSMC6 or Rpt4) of the 26S proteasome, which is a component of the 19S proteasome cap []. PSMC6 is one of the ATPases that form a heterohexameric ring for unfolding ubiquitinated proteins targeted for degradation by the proteasome.
This entry represents non-ATPase regulatory subunit 9 of the 26S proteasome (gene name PSMD9), also known as p27, which is not a component of the assembled 26S proteasome, but is a chaperone required for assembly forming part of the base assembly and of the modulator trimer complex of PSMD9 (p27), PSMC6 (Rpt4) and PSMC3 (Rpt5) [].
