Positively regulates the expression of ver-1 in the amphid sheath glia of amphid sensory neurons (PubMed:22298710). Together with ehn-3, plays a role in somatic gonad development and is required for proper gonadal primordium assembly and somatic gonad precursor cell morphology (PubMed:20026024). Expressed in the somatic gonad, hypodermis and cells in the head and tail (PubMed:20026024). Expressed in amphid and phasmid sheath glia, amphid and phasmid socket glia, and in neurons in the head (PubMed:22298710). Expressed from embryos to adults (PubMed:20026024). First expressed in somatic gonadal precursor cells during embryogenesis (PubMed:20026024). In the L2 larval stage of development, expressed in Z1.pa and Z4.ap distal tip cells and their descendants (PubMed:20026024). RNAi-mediated knockdown does not cause defects in somatic gonad development (PubMed:20026024). RNAi-mediated knockdown in a ehn-3 rd2 mutant background enhances the defects in gonadal development in the ehn-3 single mutant (PubMed:20026024). Belongs to the Ikaros C2H2-type zinc-finger protein family.
