Enables DNA binding activity. Acts upstream of or within several processes, including chorion development; labyrinthine layer development; and negative regulation of DNA-templated transcription. 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). [provided by Alliance of Genome Resources, Jul 2025]
