Transporter for the divalent cation Zn(2+) (PubMed:10681536, PubMed:29791142, PubMed:30914478). Mediates the influx of Zn(2+) into cells from extracellular space. The Zn(2+) uniporter activity is independent of H(+)-driving force, but is modulated by extracellular pH and membrane potential. Also transports other divalent cations Zn(2+), Cd2(+), Cu2(+), Co2(+) in the order of decreasing affinity, respectively (PubMed:29791142, PubMed:30914478). In the skin, aids in the differentiation of keratinocytes in the epidermis (By similarity). {ECO:0000250|UniProtKB:G3X943, ECO:0000269|PubMed:10681536, ECO:0000269|PubMed:29791142, ECO:0000269|PubMed:30914478}. This is the function of Ensembl gene identifier ENSG00000165794 (SLC39A2, solute carrier family 39 member 2).
