What is interactome meaning?
What is interactome meaning?
Definition. An interactome is a protein–protein interaction (PPI) network that contains ideally all possible PPIs in a specific organism.
What is an interactome biology?
Interactomes are dynamic protein networks in which many protein–protein interactions are context-dependent and require specific modifications and/or structural alterations of the interacting partners that only occur under the appropriate cellular conditions [11,12]. From: Trends in Biochemical Sciences, 2009.
What is interactome database?
IntAct Molecular Interaction Database IntAct provides a freely available, open source database system and analysis tools for molecular interaction data. All interactions are derived from literature curation or direct user submissions and are freely available. The IntAct Team also produces the Complex Portal.
What are Interactomes used for?
The interactome has also been used to characterise the functions of unknown proteins. Usually proteins which interact together are also likely involved in similar or same biological processes. Thus, finding the interacting partners of an unknown protein or metabolite can give indication as to its function.
What is meant by proteome?
A proteome is the complete set of proteins expressed by an organism. The term can also be used to describe the assortment of proteins produced at a specific time in a particular cell or tissue type. The proteome is an expression of an organism’s genome.
What is Interactome analysis?
Interactomics thus aims to compare such networks of interactions (i.e., interactomes) between and within species in order to find how the traits of such networks are either preserved or varied.
What is a systems biology approach?
Systems biology is an approach in biomedical research to understanding the larger picture—be it at the level of the organism, tissue, or cell—by putting its pieces together. It’s in stark contrast to decades of reductionist biology, which involves taking the pieces apart.
What is meant by intact protein?
adj untouched or unimpaired; left complete or perfect.
How many proteins are in humans?
Proteome: It is now estimated that the human body contains between 80,000 and 400,000 proteins. However, they aren’t all produced by all the body’s cells at any given time. Cells have different proteomes depending on their cell type.
Why is the proteome important?
The proteome is the complete set of proteins produced by the genome at any one time. Proteomics, the study of the proteome, is important because proteins represent the actual functional molecules in the cell. When mutations occur in the DNA, it is the proteins that are ultimately affected.
Where does the term interactome come from in science?
The interactome is the whole set of molecular interactions that occur within a particular cell. The term interactome was originally coined in 1999 by a group of French scientists headed by Bernard Jacq,133 and is often described in terms of biological networks.
How many gene interactions are there in the interactome?
In 2010, the most “complete” gene interactome produced to date was compiled from about 5.4 million two-gene comparisons to describe “the interaction profiles for ~75% of all genes in the budding yeast”, with ~170,000 gene interactions.
Why is the interactome referred to as a blueprint?
In analogy to the genome representing the blueprint for all molecular components, the collection of all their interactions is referred to as the interactome. The interactome thus represents the blueprint for the collective functions that emerge from interactions between individual components.
How are perturbations and disease related in the interactome?
Perturbations and disease. The topology of an interactome makes certain predictions how a network reacts to the perturbation (e.g. removal) of nodes (proteins) or edges (interactions). Such perturbations can be caused by mutations of genes, and thus their proteins, and a network reaction can manifest as a disease.
