Is predicted to encode a protein with the following domains: Zinc finger, RanBP2-type; Nuclear pore complex protein; Zn-finger in Ran binding protein and others; and Spt5 C-terminal nonapeptide repeat binding Spt4. Is an ortholog of C. elegans
npp-7. In C. elegans,
npp-7 is involved in several processes, including determination of adult lifespan; nucleus organization; and regulation of exit from mitosis.
