Using the Protein-protein Interaction Network to Identifying the Biomarkers in Evolution of the Oocyte
Background Oocyte maturity includes nuclear and cytoplasmic maturity, both of which are important for embryo fertilization. The development of oocyte is not limited to the period of follicular growth, and starts from the embryonic period and continues throughout life. In this study, for the purpose of evaluating the effect of the FSH hormone on the expression of genes, GEO access codes for this...
متن کاملEvolution of the yeast protein interaction network.
To study the evolution of the yeast protein interaction network, we first classified yeast proteins by their evolutionary histories into isotemporal categories, then analyzed the interaction tendencies within and between the categories, and finally reconstructed the main growth path. We found that two proteins tend to interact with each other if they are in the same or similar categories, but t...
متن کاملBackground on Protein Protein Interaction Network Evolution
Proteins are linear polymers built from 20 building blocks called amino acids. Parts of a protein that are found conserved in many other proteins are called domains; these domains are usually responsible for the protein-protein interactions. Protein-protein interactions (PPIs) are transient or permanent connections between proteins, and they are important for many biological phenomena such as s...
متن کاملThe Evolution of Protein Interaction Networks in Regulatory Proteins
Interactions between proteins are essential for intracellular communication. They form complex networks which have become an important source for functional analysis of proteins. Combining phylogenies with network analysis, we investigate the evolutionary history of interaction networks from the bHLH, NR and bZIP transcription-factor families. The bHLH and NR networks show a hub-like structure ...
متن کاملConservation of protein interaction network in evolution.
A functional analysis of protein fold interaction suggested that structural fold families have gradually acquired more diverse interacting partners while maintaining central biochemical interactions and functions. This means that the protein interaction network (map) maintains its robust architecture due to the functional constraints associated with the interactions.
