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 Defects in biotin (Btn) metabolism and Glucagon signaling pathway. 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).
