Tyrosine phosphorylation has emerged as a central event in the signal transduction pathways that regulate cell growth, differentiation, and other cellular functions. Receptor tyrosine kinases, cytoplasmic enzymes, and cytoskeletal proteins have been shown to be phosphorylated on tyrosine residues and, in some cases, a tyrosine kinase has been identified that phosphorylates a protein substrate. In the present report, we review evidence for a role of tyrosine phosphorylation in the signal transduction pathways of insulin, the growth factor platelet-derived growth factor, and the mitogenic activity of the colony-stimulating factors. These findings suggest a common pathway for the regulation of cellular functions by insulin, growth factors, and several other growth factors. We also present evidence that supports the concept that tyrosine phosphorylation may be an important mechanism by which the cross-talk between growth factors, other growth factors, hormones, and substrates modulates the response of cells to one or more growth factors.And I'm David Greene. It is 5:30. The stock market is closed. The president is in Springfield, Illinois. He's about to give a speech, and so is his vice president. I'm going to be joined by our reporters for the "CBS This Morning" team. That's because it is a presidential politics day. (COMMERCIAL BREAK) MATTHEWS: This has been an extremely important week. It's going to determine whether the stock market has a long or a short hangover. It determines whether the economy is going to start healing or starting to deteriorate. We'll explain what we know so far. Also, we're not going to hold President Obama to his promise not to cut taxes on people earning $250,000 a year. He has made a mistake. He has withdrawn the pledge. That's a mistake. We'll explain why. He should stick to it. He should make it a priority and why not keep his word. Also, we are going to see if this is a year of comeuppance for Republicans. And we'll find out from John Kerry who told us this. And I'm back with our political team. Welcome to all of you. TUCKER CARLSON, "FOX NEWS ac619d1d87
