Lcat Gene Summary [Rat]
Enables phosphatidylcholine-sterol O-acyltransferase activity and phospholipase A2 activity. Involved in several processes, including aflatoxin metabolic process; cholesterol metabolic process; and response to copper ion. Predicted to be part of high-density lipoprotein particle. Predicted to be active in extracellular space. Used to study end stage renal disease; familial hyperlipidemia; and myocardial infarction. 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, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Lcat often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
