The function of SLC39A10 (solute carrier family 39 member 10, ENSG00000196950) is as follows. Zinc-influx transporter (PubMed:17359283, PubMed:27274087, PubMed:30520657). When associated with SLC39A6, the heterodimer formed by SLC39A10 and SLC39A6 mediates cellular zinc uptake to trigger cells to undergo epithelial-to-mesenchymal transition (EMT) (PubMed:23186163). SLC39A10-SLC39A6 heterodimers play also an essential role in initiating mitosis by importing zinc into cells to initiate a pathway resulting in the onset of mitosis (PubMed:32797246). Plays an important for both mature B-cell maintenance and humoral immune responses (By similarity). When associated with SLC39A10, the heterodimer controls NCAM1 phosphorylation and integration into focal adhesion complexes during EMT (By similarity). {ECO:0000250|UniProtKB:Q6P5F6, ECO:0000269|PubMed:17359283, ECO:0000269|PubMed:23186163, ECO:0000269|PubMed:27274087, ECO:0000269|PubMed:30520657, ECO:0000269|PubMed:32797246}.
