The function of Ensembl gene identifier ENSG00000141469 (SLC14A1, solute carrier family 14 member 1 (Kidd blood group)) is as follows. Mediates the transport of urea driven by a concentration gradient across the cell membrane of erythrocytes (PubMed:10514515, PubMed:7797558, PubMed:7989337, PubMed:8997401). Also mediates the transport of urea across the cell membrane of the renal inner medullary collecting duct which is critical to the urinary concentrating mechanism (By similarity). Facilitates water transport in erythrocytes (By similarity). {ECO:0000250|UniProtKB:Q8VHL0, ECO:0000269|PubMed:10514515, ECO:0000269|PubMed:7797558, ECO:0000269|PubMed:7989337, ECO:0000269|PubMed:8997401}.
