Previous GeneCards Identifiers for ACACB Gene
Acetyl-CoA carboxylase (ACC) is a complex multifunctional enzyme system. ACC is a biotin-containing enzyme which catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the rate-limiting step in fatty acid synthesis. ACC-beta is thought to control fatty acid oxidation by means of the ability of malonyl-CoA to inhibit carnitine-palmitoyl-CoA transferase I, the rate-limiting step in fatty acid uptake and oxidation by mitochondria. ACC-beta may be involved in the regulation of fatty acid oxidation, rather than fatty acid biosynthesis. There is evidence for the presence of two ACC-beta isoforms. [provided by RefSeq, Jul 2008]
GeneCards Summary for ACACB Gene
ACACB (Acetyl-CoA Carboxylase Beta) is a Protein Coding gene. Diseases associated with ACACB include Acetyl-Coa Carboxylase-Beta Deficiency and Biotin Deficiency. Among its related pathways are Metabolism of water-soluble vitamins and cofactors and fatty acid biosynthesis initiation. GO annotations related to this gene include ligase activity and biotin binding. An important paralog of this gene is ACACA.
UniProtKB/Swiss-Prot for ACACB Gene
Catalyzes the ATP-dependent carboxylation of acetyl-CoA to malonyl-CoA. Carries out three functions: biotin carboxyl carrier protein, biotin carboxylase and carboxyltransferase. Involved in inhibition of fatty acid and glucose oxidation and enhancement of fat storage (By similarity). May play a role in regulation of mitochondrial fatty acid oxidation through malonyl-CoA-dependent inhibition of carnitine palmitoyltransferase 1 (By similarity).
