DESCRIPTION

Also known as ACACA_HUMAN, ACACA, ACAC, ACC1, ACCA. Cytosolic enzyme that catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the first and rate-limiting step of de novo fatty acid biosynthesis (PubMed:20952656, PubMed:20457939, PubMed:29899443). This is a 2 steps reaction starting with the ATP-dependent carboxylation of the biotin carried by the biotin carboxyl carrier (BCC) domain followed by the transfer of the carboxyl group from carboxylated biotin to acetyl-CoA (PubMed:20952656, PubMed:20457939, PubMed:29899443). Monomer, homodimer, and homotetramer (PubMed:20952656, PubMed:29899443). Can form filamentous polymers (PubMed:20457939, PubMed:20952656, PubMed:29899443). Interacts in its inactive phosphorylated form with the BRCT domains of BRCA1 which prevents ACACA dephosphorylation and inhibits lipid synthesis (PubMed:12360400, PubMed:16326698, PubMed:18452305, PubMed:29899443). Interacts with MID1IP1; interaction with MID1IP1 promotes oligomerization and increases its activity (PubMed:20457939).
