Predicted to enable identical protein binding activity and proteasome-activating activity. Predicted to be involved in modulation by host of viral transcription; positive regulation of transcription by RNA polymerase II; and proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within blastocyst development. Located in perinuclear region of cytoplasm. Orthologous to human PSMC3 (proteasome 26S subunit, ATPase 3).
