Members of the SLC45 family remain to be fully characterised. SLC45A1 was initially identified in the rat brain, particularly predominant in the hindbrain, as a proton-associated sugar transport, induced by hypercapnia [3]. The protein is predicted to have 12TM domains, with intracellular termini. The SLC45A2 gene is thought to encode a transporter protein that mediates melanin synthesis. Mutations in SLC45A2 are a cause of oculocutaneous albinism type 4 (e.g. [2]), and polymorphisms in this gene are associated with variations in skin and hair color (e.g. [1]).
