Summary
Predicted to be involved in melanin biosynthetic process and melanocyte differentiation. Predicted to act upstream of or within cell population proliferation; developmental pigmentation; and spermatid development. Predicted to be located in endoplasmic reticulum membrane; endosome membrane; and lysosomal membrane. Predicted to be active in melanosome membrane. Human ortholog(s) of this gene implicated in actinic keratosis; oculocutaneous albinism type II; pigmentation disease; skin cancer (multiple); and squamous cell carcinoma. Orthologous to human OCA2 (OCA2 melanosomal transmembrane protein). [provided by Alliance of Genome Resources, Apr 2022]

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.
