**Recombinant Human MPPE1 Protein: Background and Significance**
Membrane Protein Palmitoylated 1 (MPPE1), also known as Lysosome-associated apoptosis-inducing protein containing PH domains, is a conserved eukaryotic protein implicated in cellular membrane dynamics, signaling, and homeostasis. Structurally, MPPE1 contains a pleckstrin homology (PH) domain, which facilitates interactions with phosphoinositides, and a C-terminal palmitoylation site that anchors it to membranes. Its role in regulating lipid metabolism, vesicular trafficking, and apoptosis-associated pathways highlights its biological importance. Dysregulation of MPPE1 has been linked to neurodegenerative disorders and cancer progression, suggesting its potential as a therapeutic target.
Recombinant MPPE1 is produced using heterologous expression systems, such as *E. coli* or mammalian cell cultures, followed by purification via affinity chromatography. This engineered protein retains native functional properties, enabling studies on its molecular interactions, enzymatic activities, or structural characteristics. Researchers utilize recombinant MPPE1 to investigate palmitoylation mechanisms, membrane-protein interactions, and its involvement in disease pathways. Additionally, it serves as a critical tool for drug screening, antibody development, and understanding cellular responses to stress or apoptotic stimuli.
The application of recombinant MPPE1 bridges gaps in both basic and translational research, offering insights into membrane biology while supporting the discovery of targeted therapies for conditions linked to its dysfunction.
