Protein–lipid interaction is the influence of membrane proteins on the lipid physical state or vice versa.. The questions which are relevant to understanding of the structure and function of the membrane are: 1) Do intrinsic membrane proteins bind tightly to lipids (see annular lipid shell), and what is the nature of the layer of lipids adjacent to the protein?
The simulations done my PIMD can broadly characterize the biomolecular systems, covering the entire structure and organization of the membrane, including the permeability, protein-lipid interactions, along with "lipid-drug interactions, protein–ligand interactions, and protein structure and dynamics."
Graphical models have become powerful frameworks for protein structure prediction, protein–protein interaction, and free energy calculations for protein structures. Using a graphical model to represent the protein structure allows the solution of many problems including secondary structure prediction, protein-protein interactions, protein-drug interaction, and free energy calculations.
Myristoylation allows for weak protein–protein and protein–lipid interactions [5] and plays an essential role in membrane targeting, protein–protein interactions and functions widely in a variety of signal transduction pathways.

Martini is a coarse-grained (CG) force field developed by Marrink and coworkers at the University of Groningen, initially developed in 2004 for molecular dynamics simulation of lipids, [1] later (2007) extended to various other molecules. The force field applies a mapping of four heavy atoms to one CG interaction site and is parametrized with ...
The proteolipid code relies on the concept of a zone, which is a functional region of membrane that is assembled and stabilized with both protein and lipid dependency. Integral and lipid-anchored proteins are proposed to form three types of zones: proteins with an associated lipid fingerprint, [9] protein islands, and lipid-only voids. Although ...
Myristoylation is a post-translational modification marked by the covalent attachment of a myristoyl group to an N-terminal glycine residue. It allows for weak protein-protein and protein-lipid interactions. Myristoylation aids in the membrane association of Src kinases.
