Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Genetic Screens

Genetic Screens

Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

Protein-protein Interfaces

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...

Protein Complexes with Interchangeable Parts

Protein Complexes with Interchangeable Parts

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order to...

Epistasis Analysis

Epistasis Analysis

Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway. The...

Protein Complex Assembly

Protein Complex Assembly

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Summary

Predicting gene function is key in genetics. Protein complex membership accurately predicts knockout phenotypes in yeast and disease phenotypes in humans, aiding gene discovery.

Bioinformatics

Background:

Predicting the phenotypic effects of genetic mutations is crucial for understanding genotype-phenotype relationships and identifying human disease genes.
Elucidating how genetic variations influence observable traits remains a central challenge in biological and medical research.

Purpose of the Study:

To determine the most effective predictor of protein knockout phenotypes using functional genomic data.
To assess the utility of protein complex membership as a predictor of human disease phenotypes.

Main Methods:

Analysis of functional genomic data from Saccharomyces cerevisiae.
Evaluation of protein complex membership as a predictive feature for knockout phenotypes.
Assessment of protein complex proxies for predicting human disease phenotypes.

Main Results:

Protein complex membership is the strongest predictor of a protein's knockout phenotype in yeast.
Incorporating additional functional genomic datasets did not improve predictive accuracy beyond protein complex data.
A proxy for protein complexes effectively predicts human disease phenotypes.

Conclusions:

Identifying human protein complexes with known disease genes offers an efficient strategy for large-scale disease gene discovery.
The yeast Saccharomyces cerevisiae serves as a valuable model for studying and predicting the genetic basis of human diseases, including Mendelian and complex disorders.
