**Background of ACSL5 Recombinant Protein**
ACSL5 (Acyl-CoA Synthetase Long-Chain Family Member 5) is a key enzyme in lipid metabolism, catalyzing the activation of long-chain fatty acids into acyl-CoA esters. This reaction is critical for fatty acid utilization in energy production, membrane synthesis, and lipid storage. As a member of the ACSL family, ACSL5 exhibits substrate specificity for fatty acids with 12–20 carbon chains and is predominantly expressed in mitochondria-rich tissues, such as the intestine, liver, and adipose tissue. Its mitochondrial localization links it to cellular energy homeostasis and apoptosis regulation, with studies suggesting roles in modulating ceramide-induced apoptosis via interactions with pro-apoptotic proteins like Bax.
The recombinant ACSL5 protein is produced through genetic engineering, typically using bacterial (e.g., *E. coli*) or mammalian expression systems. This allows for high-purity, standardized protein production, essential for functional studies. Recombinant ACSL5 retains enzymatic activity, enabling research into its metabolic functions and dysregulation in diseases. For instance, ACSL5 overexpression has been implicated in cancers (e.g., colorectal, hepatocellular carcinoma) due to its role in promoting lipid-driven proliferation and suppressing apoptosis. Conversely, reduced ACSL5 activity is associated with metabolic disorders like obesity and insulin resistance, highlighting its dual roles in health and disease.
In research, ACSL5 recombinant protein is widely used to investigate lipid metabolism pathways, screen therapeutic inhibitors, and develop diagnostic tools. Its recombinant form also facilitates structural studies to elucidate substrate-binding mechanisms and design targeted therapies. Overall, ACSL5 serves as a vital molecular tool for understanding lipid biology and its implications in metabolic and oncogenic diseases.
