"The TGF beta receptors TGFBR1 and TGFBR2 belong to a subfamily of membrane-bound serine/threonine kinases which are designated as Type I or II based on their structural and functional properties. The receptor is composed of pairs of type I or II arranged in a heterotetrameric complex. Its ligand, TGF beta, has 3 members - TGFB1, TGFB2 and TGFB3, which can homodimerize or heterodimerize before binding to the receptors. Ligand binding activates the MAPK/SMAD signaling modules."

The TGF-beta Receptor Signaling pathway was kindly reviewed by Van Le Hong, Wei He and other members of Joan Massague’s lab. This cancer signaling pathway is available at Cancer Cell Map (http://cancer.cellmap.org) and NetPath (http://www.netpath.org) and is part of a collaborative project between the Computational Biology Center at Memorial Sloan-Kettering Cancer Center (http://cbio.mskcc.org), PandeyLab at Johns Hopkins University (http://pandeylab.igm.jhmi.edu) and Institute of Bioinformatics (http://www.ibioinformatics.org). If you use this pathway, you must cite the Cancer Cell Map and NetPath websites until the pathway is published.
