BioPAX is a collaborative effort to create a data exchange format for biological pathway data. Get involved...

BioPAX Level 2, Version 1.0

BioPAX Level 2 covers metabolic pathways, molecular interactions and protein post-translational modifications and is backwards compatible with Level 1. Future levels will expand support for signaling pathways, gene regulatory networks and genetic interactions. More...
