Introduction HE insulin-like growth factors were discovered on the II. Signal Transduction via IGF Receptors T basis of their ability to stimulate cartilage sulf ation and A. IGF-I receptor to replace the "sulfation factor activity" of GH, as determined 1. Extracellular domain/ligand binding using an in vivo assay, in an in vitro test system (1). The 2. Cytoplasmic domain biological significance of this finding was quickly expanded 3. Signal transduction beyond the study of cartilage sulf ation to include stimulation 4. Hybrid insulin/IGF-I receptors of DNA synthesis (2), proteoglycan synthesis (3), glycosami- B. IGF-II/mannose-6-phosphate receptor noglycan synthesis (4), and protein synthesis (5). Most of 1. Ligand binding these studies used tissue preparations such as isolated dia- 2. Deletion of IGF-II receptor/parental imprinting phragm, cartilage, or epididymal fat pads to study biological 3.
