SLC45A2

Proton-associated glucose and sucrose transporter (By similarity). May be able to transport also fructose (By similarity). Expressed at a late melanosome maturation stage where functions as proton/glucose exporter which increase lumenal pH by decreasing glycolysis. Regulates melanogenesis by maintaining melanosome neutralization that is initially initiated by transient OCA2 and required for a proper function of the tyrosinase TYR..
