CRAT - carnitine O-acetyltransferase Gene
Also Known as CAT; CAT1; NBIA8
Species: Homo sapiens
About CRAT
This gene has 22 transcripts (splice variants), 228 orthologues, 6 paralogues and is associated with 1 phenotype. Broad expression in testis (RPKM 76.6), duodenum (RPKM 25.0) and 23 other tissues.
Summary
This gene encodes carnitine O-acetyltransferase, a member of the carnitine Acyltransferase family and a key metabolic pathway enzyme which plays an important role in energy homeostasis and fat metabolism. This enzyme catalyzes the reversible transfer of acyl groups from an acyl-CoA thioester to carnitine and regulates the ratio of acyl-CoA/CoA. It is found in both the mitochondria and the peroxisome. Alternative splicing results in transcript variants encoding different isoforms that may localize to different subcellular compartments. [provided by RefSeq, Oct 2016]
