Is predicted to encode a protein with the following domains: Winged helix DNA-binding domain superfamily; PCI domain; 26S proteasome regulatory subunit Rpn6, N-terminal; Proteasome component (PCI) domain; 6S proteasome subunit Rpn6, C-terminal helix domain; 26S proteasome regulatory subunit RPN6 N-terminal domain; and 26S proteasome subunit RPN6 C-terminal helix domain. Is an ortholog of C. elegans rpn-6.1. In C. elegans, rpn-6.1 is involved in determination of adult lifespan; proteasome assembly; and ubiquitin-dependent protein catabolic process.
