How do you detect protein-protein interactions?
Pull-down assays Pull-down assay is an in vitro method used to determine a physical interaction between two or more proteins. It can be used for confirmation of existing protein-protein interactions discovered by other techniques or initial screening to identify novel protein-protein interactions.
What are protein interaction partners?
Protein–protein interactions (PPIs) are physical contacts of high specificity established between two or more protein molecules as a result of biochemical events steered by interactions that include electrostatic forces, hydrogen bonding and the hydrophobic effect.
What is Protein-Protein Interaction?
Protein–protein interaction networks are the networks of protein complexes formed by biochemical events and/or electrostatic forces and that serve a distinct biological function as a complex. The protein interactome describes the full repertoire of a biological system’s protein–protein interactions (PPIs).
How proteins interact with each other?
Proteins bind to each other through a combination of hydrophobic bonding, van der Waals forces, and salt bridges at specific binding domains on each protein. These domains can be small binding clefts or large surfaces and can be just a few peptides long or span hundreds of amino acids.
What is the importance of protein-protein Interaction?
Protein-protein interactions (PPIs) play a crucial role in cellular functions and biological processes in all organisms. The identification of protein interactions can lead to a better understanding of infection mechanisms and the development of several medication drugs and treatment optimization.
What factors are involved in protein-protein interactions?
Forces involved in Protein-Protein Interactions Sci. USA 1996, 93, 13–20, steric factors, hydrophobic and electrostatic interactions and hydrogen bonds all contribute to the binding interaction however it has been shown that hydrophobic forces are significant.

Why Protein Protein Interaction is important?
How many protein-protein interactions are there?
The total number of possible protein-protein interactions was estimated around 4,000, which indicates that the current protein repository contains only 42% of quaternary folds in nature and a full coverage needs approximately a quarter century of experimental effort.
How do protein microarrays work?
A protein microarray (or protein chip) is a high-throughput method used to track the interactions and activities of proteins, and to determine their function, and determining function on a large scale. Any reaction between the probe and the immobilised protein emits a fluorescent signal that is read by a laser scanner.
