Involved in the regulation of Pn.p cell fate determination (PubMed:12015965). Involved in zinc metabolism and the decrease of the cytosolic zinc concentration which is thought to modulate Ras signaling (PubMed:12015965). Involved in zinc transport from the intestinal lumen to the pseudocoelum (PubMed:23717214). Interacts with lin-45 in a zinc-dependent manner. Expressed in intestinal cells (PubMed:12015965, PubMed:23717214). Expressed in the vulva (PubMed:12015965). Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family. SLC30A subfamily.
