Is predicted to encode a protein with the following domains: Myb domain; Homeobox-like domain superfamily; Myb-like DNA-binding domain; Chaperone J-domain superfamily; DnaJ domain; and SANT/Myb domain. Is an ortholog of C. elegans dnj-28 and dnj-7. In C. elegans, dnj-7 is involved in PERK-mediated unfolded protein response.
