ACSL3 (E2S9L) Rabbit mAb recognizes endogenous levels of total ACSL3 protein.

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu529 of human ACSL3 protein.

Mammalian long-chain acyl-CoA synthetase (LACS or ACSL) catalyzes the ligation of fatty acids to CoA to form fatty acyl-CoA in a two-step reaction. Five isoforms of ACSL have been identified. These isoforms have different substrate preferences and subcellular localizations (1). Studies show that exogenous monounsaturated fatty acids inhibit ferroptosis and that this process requires the activation of monounsaturated fatty acids by acyl-CoA synthetase long-chain family member 3 (ACSL3) (2). In addition, studies on a mouse model show that Acsl3 is essential for oleic acid to protect melanoma cells from ferroptosis, which leads to more tumor metastases (3). Furthermore, ACSL3 is required for prostaglandin synthesis and tumorigenesis in non-small cell lung cancer (NSCLC) (4).
