Proteasome-dependent degradation serves an essential role in the removal of a wide variety of key nuclear and cytosolic proteins. Substrates are targeted for proteolysis by the ubiquitin pathway before being degraded by the 26 S proteasome. RPN6 associates with an ATPase subunit of the 19S proteasome regulatory complex, AtS6A. Alternative names: 19S proteosome subunit 9, 26S proteasome non-ATPase regulatory subunit 11 homolog, AtRPN6.
