Psmd4 - proteasome (prosome, macropain) 26S subunit, non-ATPase, 4

Predicted to enable identical protein binding activity and polyubiquitin modification-dependent protein binding activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process. Part of proteasome accessory complex. Is expressed in brain and surface ectoderm. Orthologous to human PSMD4 (proteasome 26S subunit ubiquitin receptor, non-ATPase 4). [provided by Alliance of Genome Resources, Apr 2022]
