Is predicted to encode a protein with the following domains: Winged helix DNA-binding domain superfamily; PCI domain; 26S Proteasome non-ATPase regulatory subunit 6; Proteasome component (PCI) domain; 26S proteasome subunit RPN7; and 26S proteasome regulatory subunit Rpn7/COP9 signalosome complex subunit 1. Is an ortholog of C. elegans rpn-7.
