Putative transcription factor (PubMed:19500563). Positive regulator of the lin-12/Notch signaling pathway (PubMed:15020414). Binds to specific DNA sequences in regulatory elements (PubMed:19500563). Involved in cell fate decisions that require cell-cell interactions, such as the anchor cell (AC) / ventral uterine (VU) precursor cell fate decision (PubMed:15020414). Heterochronic protein which controls the choice of stage specific cell fates, including the larval L3 stage-specific fate of seam cells (PubMed:19500563). Involved in regulating the temporal expression pattern of hunchback-like protein hbl-1, thereby playing a role in the progression between larval stages L2 and L3 (PubMed:19500563). Multimer (PubMed:15020414). May interact with mediator complex subunit mdt-29 (PubMed:15020414). Widely expressed, including in pharyngeal muscle cells and body wall muscle cells. Expressed in seam cells with temporal changes in expression level; undetectable in L1 and L2 larval stages, then expressed at the L3 stage, declining at the late L4 stage and expressed only weakly in young adults (PubMed:19500563). Expressed in the vulval precursor cells (VPCs) (PubMed:15020414). RNAi-mediated knockdown suppresses the hermaphrodite gonadal development and egg-laying defects in a lin-12 mutant background.
