ATP citrate-lyase is an important enzyme for cytosolic acetyl-CoA synthesis. During fatty acid synthesis, Citrate and CoA form acetyl-CoA and oxaloacetate.
ATP citrate-lyase has emerged as new target for cancer treatment. Studies have found that many types of cancer including glioblastoma, colorectal cancer, breast cancer, non-small cell lung cancer, and hepatocellular carcinoma experience abnormally high levels of ATP citrate-lyase.
