Summary: Enables phosphatidylcholine-retinol O-acyltransferase activity; retinoic acid binding activity; and retinol binding activity. Involved in response to retinoic acid; response to vitamin A; and retinol metabolic process. Located in multivesicular body; perinuclear region of cytoplasm; and rough endoplasmic reticulum. Human ortholog(s) of this gene implicated in Leber congenital amaurosis 14 and retinitis pigmentosa. Orthologous to human LRAT (lecithin retinol acyltransferase).

The results show that the major 5.3 kb transcript uses the canonical signal AAUAAA located at nt 5308, and the major short transcript of approximately 1.5 kb uses the non-canonical signal AUUAAA located at nt 1330.

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.
