The function of ENSG00000136813 (ECPAS, Ecm29 proteasome adaptor and scaffold) is as follows. Adapter/scaffolding protein that binds to the 26S proteasome, motor proteins and other compartment specific proteins. May couple the proteasome to different compartments including endosome, endoplasmic reticulum and centrosome. May play a role in ERAD and other enhanced proteolysis (PubMed:15496406). Promotes proteasome dissociation under oxidative stress (By similarity). {ECO:0000250|UniProtKB:Q6PDI5, ECO:0000269|PubMed:15496406, ECO:0000269|PubMed:20682791}.
