Enables DNA binding activity. Acts upstream of or within several processes, including chorion development; labyrinthine layer development; and protein localization to nucleus. Located in cytoplasm and nucleus. Is expressed in several structures, including extraembryonic component; hemolymphoid system; nervous system; reproductive system; and sensory organ. Human ortholog(s) of this gene implicated in autosomal dominant limb-girdle muscular dystrophy type 1. Orthologous to human DNAJB6 (DnaJ heat shock protein family (Hsp40) member B6).
