Summary: Predicted to enable cysteine transmembrane transporter activity. Involved in negative regulation of melanin biosynthetic process and pigment metabolic process involved in pigmentation. Acts upstream of or within hair follicle development and pigmentation. Predicted to be located in late endosome; lysosome; and melanosome. Predicted to be active in plasma membrane. Is expressed in thymus primordium. Orthologous to human MFSD12 (major facilitator superfamily domain containing 12). [provided by Alliance of Genome Resources, Jul 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.
