Secondary Information

Protein Function Responsible for ~70% of intracellular proteolysis,[15] proteasome complex (26S proteasome) plays a critical roles in maintaining the homeostasis of cellular proteome.
Biochemical Properties The 26S proteasome is the most downstream element of the ubiquitin-proteasome pathway of protein degradation. It is composed of the 20S core particle (CP) and the 19S regulatory particle (RP). The RP consists of 6 AAA-ATPases and at least 13 non-ATPase subunits.

Significance of PTMs When the mammalian 26S proteasome 19S RP ATPase subunit Rpt6 was phosphorylated, the activity of proteasome was regulated by cAMP-dependent protein kinase (PKA).
Additional Comments The base consists of a ring of six AAA ATPases (Subunit Rpt1-6, systematic nomenclature) and four non-ATPase subunits (Rpn1, Rpn2, Rpn10, and Rpn13). Thus, 26S protease regulatory subunit 4 (Rpt2) is an essential component of forming the base subcomplex of 19S regulatory particle.
