The function of ENSG00000132517 (SLC52A1, solute carrier family 52 member 1) is as follows. Plasma membrane transporter mediating the uptake by cells of the water soluble vitamin B2/riboflavin that plays a key role in biochemical oxidation-reduction reactions of the carbohydrate, lipid, and amino acid metabolism (PubMed:18632736, PubMed:20463145). Humans are unable to synthesize vitamin B2/riboflavin and must obtain it via intestinal absorption (PubMed:20463145). {ECO:0000269|PubMed:18632736, ECO:0000269|PubMed:20463145, ECO:0000303|PubMed:20463145}. (Microbial infection) May function as a cell receptor to retroviral envelopes similar to the porcine endogenous retrovirus (PERV-A). .
