Acyl-CoA synthetase long-chain family member 4 (ACSL4) preferentially catalyzes the formation of arachidonoyl-coenzyme A (AA-CoA) by inserting coenzyme A (CoA) into arachidonic acid (AA) (1). ACSL4-catalyzed acyl-CoAs also participate in the regulation of steroidogenesis (2), eicosanoid biosynthesis (3), and phospholipid remodeling (4). ACSL4 is an essential enzyme for the conversion of two key ferroptosis-inducing signals, oxidized arachidonic and adrenic phosphatidylethanolamines (5,6). Genome-wide CRISPR\/Cas9-based genetic screens have demonstrated that ACSL4 is an essential component for ferroptosis execution (6), and genetic or pharmacological inhibition of ACSL4 can initiate a specific anti-ferroptotic rescue pathway (5). ACSL4 expression is upregulated in ferroptosis-sensitive cancer cells compared with ferroptosis-resistant cells (7) and has been shown to predict sensitivity to ferroptosis in a panel of basal-like breast cancer cell lines (6). Moreover, high ACSL4 protein expression in hepatocellular carcinoma (HCC) clinical tissue specimens is associated with improved patient outcomes after sorafenib treatment and could serve as a predictive biomarker (8).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nACS4; ACSL4; acyl-CoA synthetase 4; acyl-CoA synthetase long chain family member 4; acyl-CoA synthetase long-chain family member 4; Arachidonate--CoA ligase; FACL4; fatty-acid-Coenzyme A ligase, long-chain 4; LACS 4; LACS4; lignoceroyl-CoA synthase; Long-chain acyl-CoA synthetase 4; long-chain fatty-acid-Coenzyme A ligase 4; Long-chain-fatty-acid--CoA ligase 4; MRX63; MRX68\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 80\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799463252137,"sku":"38493S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-38493s","provider":"Iright","version":"1.0","type":"link"}
