Automated description from the Alliance of Genome Resources (Release 7.0.0)
Predicted to enable identical protein binding activity; molecular adaptor 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; liver; and surface ectoderm. Orthologous to human PSMD4 (proteasome 26S subunit ubiquitin receptor, non-ATPase 4).
