Summary: Enables phosphatidylcholine-sterol O-acyltransferase activity and platelet-activating factor acetyltransferase activity. Involved in regulation of high-density lipoprotein particle assembly. Acts upstream of or within cholesterol metabolic process and lipoprotein biosynthetic process. Located in extracellular space. Is expressed in several structures, including alimentary system; central nervous system; eye; genitourinary system; and integumental system. Used to study Norum disease. Human ortholog(s) of this gene implicated in Norum disease and arteriosclerosis. Orthologous to human LCAT (lecithin-cholesterol acyltransferase). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in liver adult (RPKM 395.2), liver E18 (RPKM 118.1) and 3 other tissues See more

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.
