== DoMo-Pred Yeast == DoMo-Pred Yeast is a novel method for predicting physiologically relevant SH3 domain-peptide mediated protein-protein interactions in S. cerevisae using phage display data. This method uses position weight matrix models of protein linear motif preference for individual SH3 domains to scan the proteome for potential hits and then filters these hits using a range of evidence sources related to sequence-based and cellular constraints on protein interactions. By combining different peptide and protein features using multiple Bayesian models we are able to predict high confidence interactions with an overall accuracy accuracy of 0.97 [[Software/DoMo-Pred|Available from the Domo-Pred Yeast homepage]] == DoMo-Pred Human == DoMo-Pred Human is a novel method of predicting SH3 domain-peptide mediated protein-protein interactions in humans using phage display data. This method builds upon our previously published work of combining multiple binding site and full length protein features using naive Bayesian models for predicting PRM mediated interactions. This work is a novel algorithm for predicting protein interactions using network topology. We have also extended the semi-supervised training regime of multinomial naive Bayesian classifier developed for text classification to Gaussian naive Bayesian models for PPI prediction.

[[http://apps.cytoscape.org/apps/siren]] == SocialNetworkApp == The Social Network Cytoscape app creates a visual summary of how individuals are connected. Biological networks can be visualized and analyzed using Cytoscape. Often researchers want to go beyond the network of proteins or genes and also look at the inter-connectedness between colleagues and institutions. Who tends to publish together? What institutions are most collaborative? Are there inter-disciplinary connections in my institution? The app addresses these questions by building co-publication networks where the nodes represent authors, edges represent co-authorship and edge thickness represents how frequently co-authors collaborate.

The Bader Lab is involved in a number of collaborative open-source bioinformatics projects designed to make biological pathway data easy to visualize and analyze.
Contents
Biological Network Analysis and Visualization Software
Cytoscape
Cytoscape is a bioinformatics software platform for visualizing molecular interaction networks and integrating these interactions with gene expression profiles and other state data. Additional features are available as plugins. Plugins are available for network and molecular profiling analyses, new layouts, additional file format support and connection with databases. Plugins may be developed using the Cytoscape open Java software architecture by anyone and plugin community development is encouraged.
Cytoscape was originally developed at the Institute of Systems Biology and is now a collaborative effort involving many different academic and commercial groups.

NetMatch
NetMatch is a Cytoscape plugin that finds user defined network motifs in any Cytoscape network. Node and edge attributes of any type and paths of unknown length can be specified in the search.
Released by: Ferro, Giugno, Pulvirenti group, University of Catania, Bader group, University of Toronto and Shasha group, New York University.

MCODE
MCODE is a Cytoscape plugin that finds clusters (highly interconnected regions) in a network. Clusters mean different things in different types of networks. For instance, clusters in a protein-protein interaction network are often protein complexes and parts of pathways, while clusters in a protein similarity network represent protein families.
Available from the MCODE homepage
BRAIN
The Biologically Relevant Analysis of Interaction Networks (BRAIN) is a set of algorithms for predicting and analyzing protein domain-peptide ligand interactions based on experimentally known binding evidence (e.g. from protein chip or phage display experiments). BRAIN can be accessed as a Cytoscape plugin which reads peptide binding profiles and generates interactions displayed as a Cytoscape network.
Available from the BRAIN homepage
LOLA
LOLA (LOgos Look Amazing) is a tool for generating sequence logos using Position Weight Matrix based protein profiles. LOLA allows you to generate custom sequence logos by setting parameters such as logo height, trim percentage, and residue colour scheme. You can also generate "logo trees" based on clustered protein profiles to analyze binding motif classes. Sequence logos and logo trees can be saved in various formats including PDF, PNG, and JPEG.

Enrichment Map
Enrichment Map is a Cytoscape plugin for functional enrichment visualization. Enrichment results have to be generated outside Enrichment Map, using any of the available methods. Gene-sets, such as pathways and Gene Ontology terms, are organized into a network (i.e. the "enrichment map"). In this way, mutually overlapping gene-sets cluster together, making interpretation easier. Enrichment Map also enables the comparison of two different enrichment results in the same map.

WordCloud
WordCloud is a Cytoscape app that generates a visual summary of a network. It displays string attributes associated with nodes in the network as a tag cloud, where more frequent words are displayed using a larger font size. Word co-occurence in a phrase can be visualized by arranging words in clusters or as a network.

AutoAnnotate is a Cytoscape app that finds node clusters and visually annotates them with labels and groups. These visualizations provide a concise visual summary which is helpful for network analysis and interpretation.

SIREN
The Signing of Regulatory Networks (SIREN) algorithm can infer the regulatory type (positive or negative regulation) of interactions in a known gene regulatory network given corresponding genome-wide gene expression data.

SocialNetworkApp
The Social Network Cytoscape app creates a visual summary of how individuals are connected. Biological networks can be visualized and analyzed using Cytoscape. Often researchers want to go beyond the network of proteins or genes and also look at the inter-connectedness between colleagues and institutions. Who tends to publish together? What institutions are most collaborative? Are there inter-disciplinary connections in my institution? The app addresses these questions by building co-publication networks where the nodes represent authors, edges represent co-authorship and edge thickness represents how frequently co-authors collaborate.

Biological Pathway and Network Database Software
GeneMANIA
GeneMANIA helps you predict the function of your favourite genes and gene sets.
GeneMANIA finds other genes that are related to a set of input genes, using a very large set of functional association data. Association data include protein and genetic interactions, pathways, co-expression, co-localization and protein domain similarity. You can use GeneMANIA to find new members of a pathway or complex, find additional genes you may have missed in your screen or find new genes with a specific function, such as protein kinases. Your question is defined by the set of genes you input.
This work is done in collaboration with Quaid Morris' lab at the University of Toronto.
