From WikiPathways

This tutorial explains how to create a pathway on WikiPathways, using the circadian clock pathway as an example.

The circadian clock pathway

The circadian clock is a molecular mechanism that maintains the cell's 24-hour molecular rhythm by driving the rhythmic expression of a wide range of genes, involved in metabolism, physiology and behaviour. In this tutorial, you will draw a simplified version of the pathway, restricting to the mPer/mCry feedback loop.

Step by step guide to drawing the circadian clock pathway

The following pages show you step-by-step how to draw a simplified version of the circadian clock pathway as described in the section above.

• Step 1: Log in to WikiPathways
• Step 2: Create a new pathway
• Step 3: The proteins of the circadian clock pathway
• Step 4: Illustrate the E-box enhancer
• Step 5: Clock and Bmal1 dimerize and bind to the E-box element
• Step 6: Target genes are activated by the E-box element
• Step 7: The negative feedback loop
• Step 8: Draw cellular locations
• Step 9: Adding bibliography
• Step 10: Adding a description
• Step 11: Adding a curation tag

Extend and layout pathways using Cytoscape

Cytoscape is a tool for network visualization and analysis. In the following tutorials we will highlight some of the Cytoscape functionality that is relevant for the pathways as used on WikiPathways. For tutorials of other Cytoscape features, please see the Cytoscape Presentations. The following tutorials will show a few Cytoscape apps at work: WikiPathways, Agilent Literature Search, CyTargetLinker and Mosaic.
