Mitogen-activated protein kinases (MAPKs) are activated by various extracellular stimuli. The signaling pathways from G protein-coupled receptors to extracellular signal-regulated kinase have been partially elucidated, whereas the mechanisms by which G protein-coupled receptors stimulate c-Jun N-terminal kinase (JNK) and p38 MAPK activities remain largely unknown. We have recently demonstrated that the signal from Gq/11-coupled m1 muscarinic acetylcholine receptor to p38 MAPK is mediated by both Galphaq/11 and Gbeta gamma in HEK-293 cells (Yamauchi, J., Nagao, M., Kaziro, Y., and Itoh, H. (1997) J. Biol. Chem. 272, 27771-27777). In the present study, we report that a constitutively activated mutant of Galpha11 (Galpha11 Q209L) activated not only p38 MAPK, but also JNK, and the activation of JNK and p38 MAPK by Galpha11 Q209L was partially inhibited by prolonged treatment with phorbol 12-myristate 13-acetate and calphostin C. In addition, the Galpha11 Q209L-stimulated activation of both kinases was blocked by a specific inhibitor of protein tyrosine kinases (PP2) and Csk (C-terminal Src kinase). Furthermore, we demonstrated that Galpha11 Q209L stimulated Src family kinase activity and induced tyrosine phosphorylation of several proteins in HEK-293 cells. These results suggest that Galphaq/11 stimulates JNK and p38 MAPK activities through protein kinase C- and Src family kinase-dependent signaling pathways.

D011493 Protein Kinase C An serine-threonine protein kinase that requires the presence of physiological concentrations of CALCIUM and membrane PHOSPHOLIPIDS. The additional presence of DIACYLGLYCEROLS markedly increases its sensitivity to both calcium and phospholipids. The sensitivity of the enzyme can also be increased by PHORBOL ESTERS and it is believed that protein kinase C is the receptor protein of tumor-promoting phorbol esters.

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
