There is now compelling evidence that the β subunit of the insulin receptor is an insulin-regulated, tyrosine-specific protein kinase. Some of this evidence is detailed in the previous chapters of this volume (Chapter 4). Data from our own laboratory on this point include the following ...
How do protein kinases affect enzymes? How do enzymes increase the rate of a chemical reaction? Explain the role of hepatocytes in the metabolism of carbohydrates, proteins, and lipids. What enzymes are used in cellular respiration? Explain how enzymes are able to make reactions go faster by di...
Sodhi, "Growth hormone-induced production of cytokines in murine peritoneal macrophages in vitro: Role of JAK/STAT, PI3K, PKC and MAP kinases," Immunobiology, vol. Future Directions and Molecular Basis of Ventilator Associated Pneumonia Protein kinase C (PKC) is a family of serine/threonine kinas...
Since their discovery in the late 1970s, protein kinase C (PKC) isozymes represent one of the most extensively studied signaling kinases. PKCs signal through multiple pathways and control the expression of genes relevant for cell cycle progression, tumorigenesis and metastatic dissemination. Despite the...
Mos, a protein kinase, is specifically expressed and functions during meiotic maturation (or G2/M progression) of vertebrate oocytes. When expressed ectopically, however, it can also readily induce oncogenic transformation (or uncontrolled G1/S transitions) in somatic cells. In both of these cell...

What are protein kinases and how do they fit into the three phases of cellular communication? In what organism were Toll proteins first discovered? What is the monomer (building block unit) of proteins? Which one of the following groups can be covalently atta...
Given the importance of menstrual blood in the pathogenesis of endometriosis and the multifunctional roles of menstrual mesenchymal stem cells (MenSCs) in regenerative medicine, this issue has gained prominence in the scientific community. Moreover, rece

One lobe is almost exclusively constituted by the single Tra1 protein (see above) whereas all other subunits are located in the main lobe. In its center, the core module of SAGA is formed by an intricate assembly of 9 subunits which tethers all other modules to the complex. Each module ...
