Probable transcription factor (PubMed:14993191, PubMed:20553900). Binds to the DNA sequence motif 5'-[TA]TGTT[TG]T[TG][ATG]TT-3' (PubMed:20553900). Regulates sexual dimorphism in the gonad, promoting male gonadal cell fates in chromosomally (XO) male animals, yet plays a role in gonadogenesis in both sexes; probably acts downstream of terminal regulator of sex determination tra-1, to control early gonadogenesis (PubMed:14993191). Positively modulates expression of homeobox protein egl-5, probably acting indirectly, during early gonadal development (PubMed:20553900). Expressed in the somatic gonadal precursor cells, Z1 and Z4, of XO and XX L1 stage larvae (PubMed:14993191). Expression is sexually dimorphic later in larval L1 stage and appears to be gonad-specific (PubMed:14993191).
