ACSS1 Protein, Human (P.pastoris, His)

ACSS1 Protein, Human (P.pastoris, His) is a mitochondrial matrix enzyme that is expressed in heart, skeletal muscle and brown adipose tissue. ACSS1 Protein, Human is involved in acetate-mediated epigenetic regulation.

Acyl-CoA short-chain synthetases (ACSS1, ACSS2, ACSS3) are the only known mammalian enzymes that can convert free acetate into acetyl-CoA. ACSS1 and ACSS2 predominantly utilize acetate as substrate, whereas ACSS3 preferentially uses propionate. The activity of these enzymes is regulated, in part, by acetylation and deacetylation of specific lysine sites. Acetylation inactivates both ACSS1 and ACSS2, whereas deacetylation reactivates them. ACSS1 is a mitochondrial matrix enzyme that is strongly expressed in heart, skeletal muscle and brown adipose tissue. This isoform primarily generates acetyl-CoA that will enter the citric acid cycle for energy derivation via oxidation to CO2^[1].
