**Background of LPCAT1 Recombinant Protein**
Lysophosphatidylcholine acyltransferase 1 (LPCAT1) is a key enzyme in phospholipid remodeling, catalyzing the conversion of lysophosphatidylcholine (LPC) to phosphatidylcholine (PC) by transferring acyl groups during the Lands cycle. This process is critical for maintaining membrane phospholipid homeostasis, influencing membrane fluidity, and regulating lipid-mediated signaling pathways. LPCAT1 is highly expressed in tissues with active lipid metabolism, such as the lungs, liver, and brain, and plays a vital role in pulmonary surfactant synthesis, a lipoprotein complex essential for respiratory function.
Dysregulation of LPCAT1 has been implicated in various pathological conditions. Overexpression of LPCAT1 is observed in multiple cancers, including hepatocellular carcinoma, lung adenocarcinoma, and glioblastoma, where it promotes tumor progression by enhancing lipid biosynthesis, activating pro-oncogenic signaling (e.g., EGFR and PI3K/AKT pathways), and facilitating membrane remodeling for rapid cell proliferation. Conversely, reduced LPCAT1 activity is linked to pulmonary disorders, such as acute respiratory distress syndrome (ARDS), due to impaired surfactant production.
Recombinant LPCAT1 protein is produced via heterologous expression systems (e.g., *E. coli*, yeast, or mammalian cells*) to study its enzymatic mechanisms, substrate specificity, and interactions with inhibitors or modulators. Its purified form enables *in vitro* assays to screen potential therapeutic agents targeting lipid metabolism disorders or cancer. Structural studies using recombinant LPCAT1 have also provided insights into its catalytic domains and regulatory regions, aiding the design of selective inhibitors.
Overall, LPCAT1 recombinant protein serves as a vital tool for investigating lipid biology, disease mechanisms, and drug development strategies.
