    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • acetyl-CoA carboxylase alpha, biotin dependent
  • catalyzing the synthesis of malonyl-CoA, an intermediate substrate playing a pivotal role in the regulation of fatty acid metabolism and energy production
  • major regulatory enzyme of fatty acid biosynthesis
  • crucial roles in de novo fatty acid biosynthesis and lipogenesis and essential for cancer cell survival
  • involved in the biosynthesis of fatty acids, and malonyl-CoA produced is used as a building block to extend the chain length of fatty acids by fatty acid synthase (FAS)
  • with FABP2 are both key factors of lipogenesis and transport
  • essential role for ACACA-mediated de novo lipogenesis as a regulator of CD8(+) T cell expansion
  • ACACA and ACLY regulate the levels of ETV4 under hypoxia via increased alpha-ketoglutarate
    metabolism energetic , lipid/lipoprotein
    a component
    small molecule cofactor,
  • biotin
  • protein
  • interacting with BRCT domain of BRCA1, and affecting lipogenesis
  • regulated at a tertiary level by MID1IP1, which facilitates ACACA polymerization and enhances enzymatic activity
  • PRKAA1 might regulate NADPH homeostasis by inhibiting ACACA and ACACB
  • PRKAA1-mediated inhibition of ACACA is required to maintain the NADPH and reactive oxygen species levels after matrix detachment
  • renin synthesis and secretion are regulated by PRKAA1 and coupled to metabolism by phosphorylation of ACACA
  • cell & other
