Structural and functional properties of platelet-derived growth factor and stem cell factor receptors.
The receptors for platelet-derived growth factor (PDGF) and stem cell factor (SCF) are members of the type III class of PTK receptors, which are characterized by five Ig-like domains extracellularly and a split kinase domain intracellularly. The receptors are activated by ligand-induced dimerization, leading to autophosphorylation on specific tyrosine residues. Thereby the kinase activities of ...
متن کاملPlatelet-derived growth factor.
Platelet-derived growth factor was purified from fresh platelets by a large-scale procedure not involving the use of SDS (sodium dodecyl sulphate). The product, 0.5 mg of platelet-derived growth factor, obtained from about 3 x 1013 platelets migrated as a single component in analytical gel electrophoresis in the presence of SDS and showed no inhomogeneity on sedimentation-equilibrium analysis i...
متن کاملPlatelet-Derived Growth Factor signaling and the role of cellular crosstalk in functional muscle growth.
Increasing the understanding of the molecular and cellular players involved in the regulation of adult skeletal muscle mass is an important open issue in current muscle biology. Muscle mass is regulated through a delicate balance between protein synthesis and protein breakdown. Under conditions of muscle hypertrophy, protein synthesis exceeds protein breakdown, resulting in an increase in the s...
متن کاملPlatelet-derived Growth Factor Stimulates the Release
The mitogenic action of growth factors involves the stimulation of intracellular protein kinases. In this report we have characterized the major protein kinase released from Balb/c 3T3 and normal rat kidney plasma membranes by the action of platelet-derived growth factor (PDGF). PDGF appears to stimulate the release of approximately 10 proteins, at least one of which is a kinase capable of ph...
متن کاملCharacterization of platelet-derived growth factor and platelet-derived growth factor receptor expression in asbestos-induced rat mesothelioma.
Although altered expression of platelet-derived growth factor (PDGF) is a hallmark of human mesothelioma, expression of PDGF receptors has not been characterized in this cell type. In addition, the expression of this growth factor and its cognate receptor in rodent mesothelioma has not been investigated. In this study, examination of transformed mesothelial cells derived from asbestos-induced r...
