Predicted to enable identical protein binding activity and proteasome-activating activity. Predicted to be involved in positive regulation of RNA polymerase II transcription preinitiation complex assembly; positive regulation of inclusion body assembly; and ubiquitin-dependent ERAD pathway. Part of proteasome accessory complex. Is expressed in several structures, including brain; genitourinary system; gut; integumental system; and vascular system. Orthologous to human PSMC6 (proteasome 26S subunit, ATPase 6). [provided by Alliance of Genome Resources, Apr 2022]
