Summary
A new method, MEDELLER, improves membrane protein (MP) structure prediction. This tool offers higher accuracy than existing methods for these important drug targets, advancing structural biology.
Area of Science:
- Structural Biology
- Computational Biology
- Biophysics
Background:
- Membrane proteins (MPs) are crucial drug targets, yet their structural data is scarce.
- Current homology-based structure prediction methods are unsuitable for MPs.
- Growing MP structure data necessitates specialized prediction tools.
Purpose of the Study:
- To develop a novel homology-based method for membrane protein structure prediction.
- To enhance the accuracy and reliability of predicted MP models.
Main Methods:
- MEDELLER, a new MP-specific homology-based coordinate generation method.
- Optimization focused on generating highly reliable core models.
- Implementation in Python, Bash, and Perl CGI for Linux systems.
Main Results:
- MEDELLER outperforms the standard Modeller program for MP structure prediction.
- Comparison on 616 target-template pairs showed superior performance.
- MEDELLER achieved an average backbone RMSD of 2.62 Å, compared to 3.16 Å for Modeller.
Conclusions:
- MEDELLER provides a significant advancement in predicting membrane protein structures.
- The method offers improved accuracy, particularly for easier prediction targets.
- MEDELLER is a valuable tool for structural biology research and drug discovery.

Membrane Proteins
Plasma membranes have integral transmembrane proteins involved in facilitated transport. These proteins are collectively referred to as transport proteins, and they function as either channels for the material or as carriers themselves. Channel proteins have hydrophilic domains exposed to the intracellular and extracellular fluids and a hydrophilic channel through their core that provides a hydrated opening for solutes to pass through the membrane layers. Passage through the channel allows...

Mechanisms of Membrane Domain Formation
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with cytoskeletal...

Fluid Mosaic Model
Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich with the analogy of...
Molecular Models
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.
Membrane Asymmetry Regulating Transporters
Enzymes like flippase, floppase, and scramblase transfer phospholipids from one layer to another in the membrane, thereby affecting membrane asymmetry.
Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
