Preferred Label : PDGF Signaling Pathway;
Alternative definition : BIOCARTA: Platelet Derived Growth Factor (PDGF) plays a critical role in cellular
proliferation and development. The biologically active form is a dimer formed from
the A and B chains. PDGF is active to a differing degree depending on which dimer
is formed (AA, AB, or BB). The PDGF Receptor (PDGFR) is also a dimer and can form
from the combination of the alpha and beta chains in any order (alpha-alpha, alpha-beta,
beta-beta). The PDGFR dimer is only formed after ligand binding so the alpha/beta
composition of the receptor can be influenced by the form of PDGF that is present.
Upon binding of ligand the PDGFR is tyrosine phosphorylated and leads to the phosphorylation
of several other cellular proteins. (This definition may be outdated - see the DesignNote.);
