该研究通过重组蛋白表达技术解析了LPP1的跨膜结构域和催化核心,发现其具有广谱磷脂磷酸酶活性,但对鞘氨醇-1-磷酸(S1P)亲和力较低。
Phosphatidic Acid Phosphatase Type 2A (PPAP2A), also known as LPP1 or Lipid Phosphate Phosphatase 1. is a membrane-associated enzyme belonging to the phosphatidate phosphatase family. It catalyzes the dephosphorylation of lipid phosphates, including lysophosphatidic acid (LPA), sphingosine-1-phosphate (S1P), and diacylglycerol pyrophosphate, generating bioactive lipid mediators that regulate cellular processes such as proliferation, migration, and survival. PPAP2A plays a critical role in lipid metabolism and signaling transduction by modulating extracellular concentrations of these signaling molecules, thereby maintaining lipid homeostasis and preventing excessive cellular responses.
This protein is integral to cardiovascular and immune functions, with studies implicating its activity in atherosclerosis, inflammation, and cancer progression. Its expression is tissue-specific, predominantly observed in the heart, skeletal muscle, and placenta. Dysregulation of PPAP2A has been linked to metabolic disorders, fibrosis, and impaired insulin sensitivity, highlighting its therapeutic potential.
Recombinant human PPAP2A protein is typically produced using expression systems like *E. coli* or mammalian cells, enabling structural and functional studies. Its recombinant form facilitates research into enzyme kinetics, substrate specificity, and inhibitor screening, advancing drug development for lipid-related diseases. The protein’s conserved catalytic domain and post-translational modifications make it a valuable tool for elucidating lipid signaling pathways and designing targeted therapies.
