Summaries for CPT1B Gene

Entrez Gene Summary for CPT1B Gene

  • 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. [provided by RefSeq, Jun 2009]

GeneCards Summary for CPT1B Gene

CPT1B (Carnitine Palmitoyltransferase 1B) is a Protein Coding gene. Diseases associated with CPT1B include Cpt Deficiency, Hepatic, Type Ia and Carnitine Palmitoyltransferase Ii Deficiency. Among its related pathways are Development_Leptin signaling via PI3K-dependent pathway and Glucagon signaling pathway. GO annotations related to this gene include transferase activity, transferring acyl groups and carnitine O-palmitoyltransferase activity. An important paralog of this gene is CRAT.
