Notes |
|
ACC1 (rat 2345-aa, human 2345-aa, ~265 kDa, chromosome 17q21) is also known as ACC-alpha is a cytosolic enzyme, enriched in liver, adipose and lactating mammary tissues. ACC-1 from rat, human, chicken are over 90% identical. ACC1 catalyzes the carboxylation of acetyl-CoA to form malonyl-CoA, the rate-limiting step in the biogenesis of LCFA-CoA. ACC1 carries three functions: biotin carboxyl carrier protein, biotin carboxylase, and carboxyltransferase (catalytic activity). Two variants of ACC-1 have been described: one with 8 additional amino acids commencing at Pro-1196, and the other which is 59 aa shorter than the predominant fat and liver isoform exist in mammals. The presence of 8 additional amino acids inhibits the in vitro phosphorylation of the Ser1200 by camp-dependent kinase. The two ACC1 isoform are differentially regulated in a tissue specific manner and under different physiological conditions. The activity of ACC1 is finely regulated by hormone dependent phosphorylation and dephosphorylation
