Neuron-specific proton-associated hexose transporter, which mediates hexose efflux from lysosomes (PubMed:28434495, PubMed:41576950). Hexose efflux is required for the stability of the vacuolar ATPase (V-ATPase) complex on the lysosomal membrane (PubMed:41576950). {ECO:0000269|PubMed:28434495, ECO:0000269|PubMed:41576950}. This is the function of SLC45A1 (solute carrier family 45 member 1, ENSG00000162426).
