What is molecular docking in drug discovery?

Molecular docking is a method which analyses the conformation and orientation (referred together as the “pose”) of molecules into the binding site of a macromolecular target. Searching algorithms generate possible poses, which are ranked by scoring functions [1].

Which protein is called docking?

Docking proteins associated with activated RTKs include FGF receptor substrate 2 (FRS2α), insulin receptor substrate 1 (IRS1), and the Grb2 (Growth factor receptor bound protein 2)-associated binder (Gab1).

Can a protein be a ligand?

Although there are many different ligands located outside of the cell, membrane proteins are specific, and only certain ligands will bind to each one. That is why each protein has a different ligand, and also induces a different cellular response.

Why do we do molecular docking?

Molecular docking is a key tool in structural molecular biology and computer-assisted drug design. The goal of ligand-protein docking is to predict the predominant binding mode(s) of a ligand with a protein of known three-dimensional structure.

What are the two steps in protein docking?

Given an experimentally determined structure of the protein, in the first stage a large number of plausible ligand conformations is generated using the fast docking algorithm FlexX. In the second stage these conformations are minimized and reranked using a method based on a classical force field.

What is the function of docking protein?

Docking proteins comprise a distinct category of intracellular, noncatalytic signalling protein, that function downstream of a variety of receptor and receptor-associated tyrosine kinases and regulate diverse physiological and pathological processes.

What holds a protein and ligand together?

A protein–ligand complex is a complex of a protein bound with a ligand that is formed following molecular recognition between proteins that interact with each other or with various other molecules. Molecular recognition depends on affinity and specificity.
