Summary

ACSS2 (acyl-CoA synthetase short chain family member 2, HGNC:15814) is a protein-coding gene on chromosome 20q11.22, encoding Acetyl-coenzyme A synthetase, cytoplasmic (Q9NR19). Catalyzes the synthesis of acetyl-CoA from short-chain fatty acids.

This gene encodes a cytosolic enzyme that catalyzes the activation of acetate for use in lipid synthesis and energy generation. The protein acts as a monomer and produces acetyl-CoA from acetate in a reaction that requires ATP. Expression of this gene is regulated by sterol regulatory element-binding proteins, transcription factors that activate genes required for the synthesis of cholesterol and unsaturated fatty acids. Alternative splicing results in multiple transcript variants.

Literature-anchored findings (GeneRIF, showing 29)

  • Because the activity of a bacterial ortholog of AceCS2, called ACS, is controlled via deacetylation by a bacterial sirtuin protein, our observation highlights the conservation of a metabolic regulatory pathway from bacteria to humans (PMID:16788062)
  • The patterns of (18)F-FDG and (11)C-acetate uptake seemed to complement each other in both human HCC and HCC cell lines. (PMID:19617323)
  • Ritonavir (at 100 mg once daily and 100 mg twice daily significantly down-regulated acyl-CoA synthetase short-chain family member 2 in 20 healthy individuals. (PMID:20353815)
  • During hypoxia, ACSS2 modulates interactions of the acetylase/coactivator CBP with the stress-responsive transcription factor, HIF-2. These interactions include acetylation of HIF-2 by CBP as well as stable HIF-2/CBP complex formation, both of which are required for maximal HIF-2 signaling. Thus, ACSS2 links changes in metabolism that occur during stress with activation of a selective nuclear signaling pathway. (PMID:25108527)
  • Observations suggest that ACSS2 is expressed to a significant extent in particular tumor types, including triple-negative breast cancers. (PMID:25525877)
  • Study shows that ACSS2 is upregulated in the human orthotopic tumor and primary human tumors, as well as a murine glioma model; the tumors do not oxidize [U-(13)C]glutamine. In vivo oxidation of [1,2-(13)C]acetate was validated in brain tumor patients and was correlated with expression of acetyl-CoA synthetase enzyme 2, ACSS2. (PMID:25525878)
  • Study revealed that the activity of acetyl-CoA synthetase 2 (ACSS2) contributes to cancer cell growth under low-oxygen and lipid-depleted conditions. (PMID:25584894)
  • Loss of ACSS2 expression is associated with with gastric cancer. (PMID:26381042)

Function. Catalyzes the synthesis of acetyl-CoA from short-chain fatty acids. Acetate is the preferred substrate. Can also utilize propionate with a much lower affinity. Catalyzes the conversion of lactate into lactoyl-CoA. Does not catalyze the conversion of butyrate or crotonate to their corresponding acyl-CoAs. Nuclear ACSS2 promotes glucose deprivation-induced lysosomal biogenesis and autophagy, tumor cell survival and brain tumorigenesis. Glucose deprivation results in AMPK-mediated phosphorylation of ACSS2 leading to its translocation to the nucleus where it binds to TFEB and locally produces acetyl-CoA for histone acetylation in the promoter regions of TFEB target genes thereby activating their transcription. The regulation of genes associated with autophagy and lysosomal activity through ACSS2 is important for brain tumorigenesis and tumor survival. Acts as a chromatin-bound transcriptional coactivator that up-regulates histone acetylation and expression of neuronal genes. Can be recruited to the loci of memory-related neuronal genes to maintain a local acetyl-CoA pool, providing the substrate for histone acetylation and promoting the expression of specific genes, which is essential for maintaining long-term spatial memory.

Subunit / interactions. Monomer. Interacts with TFEB. AMPK-mediated phosphorylated form at Ser-659 interacts with KPNA1; this interaction results in nuclear translocation of ACSS2. Interacts with the ‘Thr-172’ phosphorylated form of PRKAA2. Interacts with CREBBP.

Subcellular location. Cytoplasm. Cytosol. Nucleus.

Post-translational modifications. Reversibly acetylated at Lys-661. The acetyl-CoA synthase activity is inhibited by acetylation and activated by deacetylation mediated by the deacetylases SIRT1 and SIRT3. Glucose deprivation results in its AMPK-dependent phosphorylation at Ser-659, which leads to exposure of its nuclear localization signal, required for its interaction with KPNA1 and subsequent translocation to the nucleus.

Activity regulation. Inhibited by acetylation at Lys-661 and activated by deacetylation mediated by the deacetylases SIRT1 and SIRT3.

Similarity. Belongs to the ATP-dependent AMP-binding enzyme family.
