Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in transdifferentiation. Acts upstream of with a positive effect on multicellular organismal-level water homeostasis. Located in cytosol and nucleus. Expressed in body wall musculature;
hyp7 syncytium; intestine; and neurons. Human ortholog(s) of this gene implicated in X-linked deafness 2. Is an ortholog of human POU3F1 (POU class 3 homeobox 1); POU3F3 (POU class 3 homeobox 3); and POU3F4 (POU class 3 homeobox 4).
