ID:ACACA_HUMAN DESCRIPTION: RecName: Full=Acetyl-CoA carboxylase 1; Short=ACC1; EC=6.4.1.2; AltName: Full=ACC-alpha; Includes: RecName: Full=Biotin carboxylase; EC=6.3.4.14; FUNCTION: Catalyzes the rate-limiting reaction in the biogenesis of long-chain fatty acids. Carries out three functions: biotin carboxyl carrier protein, biotin carboxylase and carboxyltransferase. CATALYTIC ACTIVITY: ATP + acetyl-CoA + HCO(3)(-) = ADP + phosphate + malonyl-CoA. CATALYTIC ACTIVITY: ATP + biotin-[carboxyl-carrier-protein] + CO(2) = ADP + phosphate + carboxy-biotin-[carboxyl-carrier- protein]. COFACTOR: Biotin. COFACTOR: Binds 2 manganese ions per subunit. ENZYME REGULATION: By phosphorylation (By similarity). Activity is increased by oligomerization. Citrate and MID1IP1 promote oligomerization. PATHWAY: Lipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from acetyl-CoA: step 1/1. SUBUNIT: Monomer, homodimer, and homotetramer. Can form filamentous polymers. Interacts in its inactive phosphorylated form with the BRCT domains of BRCA1 which prevents ACACA dephosphorylation and inhibits lipid synthesis. Interacts with MID1IP1; interaction with MID1IP1 promotes oligomerization and increases its activity. INTERACTION: O60218:AKR1B10; NbExp=4; IntAct=EBI-717681, EBI-1572139; P38398:BRCA1; NbExp=2; IntAct=EBI-717681, EBI-349905; Q96EB6:SIRT1; NbExp=3; IntAct=EBI-717681, EBI-1802965; SUBCELLULAR LOCATION: Cytoplasm. TISSUE SPECIFICITY: Expressed in brain, placental, skeletal muscle, renal, pancreatic and adipose tissues; expressed at low level in pulmonary tissue; not detected in the liver. PTM: Phosphorylation on Ser-1263 is required for interaction with BRCA1. DISEASE: Defects in ACACA are a cause of acetyl-CoA carboxylase 1 deficiency (ACACAD) [MIM:613933]; also known as ACAC deficiency or ACC deficiency. An inborn error of de novo fatty acid synthesis associated with severe brain damage, persistent myopathy and poor growth. SIMILARITY: Contains 1 ATP-grasp domain. SIMILARITY: Contains 1 biotin carboxylation domain. SIMILARITY: Contains 1 biotinyl-binding domain. SIMILARITY: Contains 1 carboxyltransferase domain. SEQUENCE CAUTION: Sequence=AAP94120.1; Type=Erroneous initiation; WEB RESOURCE: Name=Wikipedia; Note=Acetyl-CoA carboxylase entry; URL="http://en.wikipedia.org/wiki/Acetyl-CoA_carboxylase";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
