Probable transcription factor, modulating expression of helix-loop-helix protein mbr-1, perhaps acting in concert with homeobox protein ceh-14 (PubMed:22207033). May play a minor role in axon guidance in the DVC interneuron (PubMed:22207033). May interact with homeobox protein ceh-14. First expressed in comma stage embryos, continuing into young adult hermaphrodites (PubMed:22207033). Expressed in the single interneuron DVC, in the tail ganglion, from larval L3 stage and throughout lifetime (PubMed:22207033). Expressed in the ut2 and ut3 cells in the uterus in young adults (PubMed:22207033).
