CPT1B, Official Symbol CPT1Bprovided by HGNC Official Full Name carnitine palmitoyltransferase 1Bprovided by HGNC Primary source HGNC:HGNC:2329 See related Ensembl:ENSG00000205560 MIM:601987; AllianceGenome:HGNC:2329 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as CPTI; CPT1M; MCPT1; CPT1-M; CPTI-M; M-CPT1; MCCPT1 Summary The protein encoded by this gene, a member of the carnitine/choline acetyltransferase family, is the rate-controlling enzyme of the long-chain fatty acid beta-oxidation pathway in muscle mitochondria. This enzyme is required for the net transport of long-chain fatty acyl-CoAs from the cytoplasm into the mitochondria. Multiple transcript variants encoding different isoforms have been found for this gene, and read-through transcripts are expressed from the upstream locus that include exons from this gene.
