The AGC Kinase MtIRE: A Link to Phospholipid Signaling During Nodulation?
The development of nitrogen fixing root nodules is complex and involves an interplay of signaling processes. During maturation of plant host cells and their endocytosed rhizobia in symbiosomes, host cells and symbiosomes expand. This expansion is accompanied by a large quantity of membrane biogenesis. We recently characterized an AGC kinase gene, MtIRE, that could play a role in this expansion....
متن کاملAn IRE-like AGC kinase gene, MtIRE, has unique expression in the invasion zone of developing root nodules in Medicago truncatula.
The AGC protein kinase family (cAMP-dependent protein kinases A, cGMP-dependent protein kinases G, and phospholipid-dependent protein kinases C) have important roles regulating growth and development in animals and fungi. They are activated via lipid second messengers by 3-phosphoinositide-dependent protein kinase coupling lipid signals to phosphorylation of the AGC kinases. These phosphorylate...
متن کاملAGC protein kinase phosphorylation and protein kinase C.
Protein kinase cascades feature in many signal transduction pathways. For those discussed here, a single upstream protein kinase appears to be responsible for the control of multiple downstream targets. So how is specificity introduced into these events? For the downstream kinases (substrates) described here, it would appear that specificity is determined by substrate-directed events that are p...
متن کاملPDK1, the master regulator of AGC kinase signal transduction.
The interaction of insulin and growth factors with their receptors on the outside surface of a cell, leads to the activation of phosphatidylinositol 3-kinase (PI 3-kinase) and generation of the phosphatidylinositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3) second messenger at the inner surface of the cell membrane. One of the most studied signalling events controlled by PtdIns(3,4,5)P3, comprises t...
متن کاملTORC2 and the AGC kinase Gad8 regulate phosphorylation of the ribosomal protein S6 in fission yeast
TOR (Target Of Rapamycin) signalling coordinates cell growth and division in response to changes in the nutritional environment of the cell. TOR kinases form two distinct complexes: TORC1 and TORC2. In mammals, the TORC1 controlled S6K1 kinase phosphorylates the ribosomal protein S6 thereby co-ordinating cell size and nutritional status. We show that the Schizosaccharomyces pombe AGC kinase Gad...
