Yeast Signaling01:28

Yeast Signaling

Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
Protein Networks02:26

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,...
Genome Annotation and Assembly03:36

Genome Annotation and Assembly

The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
Protein-protein Interfaces02:04

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...

Area of Science:

  • * Molecular and Systems Biology
  • * Bioinformatics and Computational Biology

Background:

  • * Existing protein-protein interaction (PPI) databases lack unified network topology and detailed biological annotations for yeast.
  • * There is a need for a comprehensive, protein-centric resource integrating large-scale network data with biophysical and regulatory information.

Purpose of the Study:

  • * To develop the ANnotated Yeast Interactome (ANYI), an integrated resource for yeast PPI data.
  • * To combine network topology with extensive annotations (e.g., protein abundance, half-life, stability, PTMs) in a unified framework.
  • * To facilitate systematic cross-layer analyses of the yeast interactome.

Main Methods:

  • * Integrated experimental yeast PPI data with sixteen types of feature annotations.
  • * Developed a unified matrix of 3,927 proteins and 155 annotation features.
  • * Created an interactive network browser for data visualization and accessibility.

Main Results:

  • * ANYI successfully integrates diverse yeast PPI and protein feature data.
  • * The resource enables systematic investigation of relationships between network properties and protein characteristics.
  • * Users can analyze correlations between protein connectivity and features like stability or disorder.

Conclusions:

  • * ANYI provides a valuable, open-access resource for yeast interactome research.
  • * The integrated framework facilitates novel discoveries in yeast systems biology.
  • * ANYI empowers computational scientists to explore complex protein interaction networks and associated features.
