Summary: Enables D-glucose:proton symporter activity and sucrose:proton symporter activity. Involved in developmental pigmentation; lysosomal lumen pH elevation; and melanin biosynthetic process from tyrosine. Acts upstream of or within sucrose transport. Predicted to be located in melanosome membrane. Predicted to be active in membrane. Is expressed in brain; embryo ectoderm; eye; mesenchyme derived from neural crest; and skin. Used to study oculocutaneous albinism. Human ortholog(s) of this gene implicated in oculocutaneous albinism type IV and pigmentation disease. Orthologous to human SLC45A2 (solute carrier family 45 member 2). [provided by Alliance of Genome Resources, Mar 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
