The PANTHER Pathway  ontology contains data primarily on signaling pathways. PANTHER pathways are collections of biological molecules and the reactions in which they participate. Only well-documented reactions and relationships are listed.
Statistics can now be found in the footers of each table in the GREAT web output.
All ontology data was downloaded and built between Oct 14, 2011 and Feb 18, 2012.
GREAT v1.8 PANTHER Pathway statistics are available here.
GREAT v1.2 PANTHER Pathway statistics are available here.
