Is predicted to encode a protein with the following domains: TANGO6/Rtp1; Required for nuclear transport of RNA pol II C-terminus 2; Armadillo-like helical; Required for nuclear transport of RNA pol II C-terminus 1; RNA polymerase II assembly factor Rtp1, C-terminal domain 2; RNA polymerase II assembly factor Rtp1, C-terminal; and Armadillo-type fold. Is an ortholog of C. elegans ekl-6.
