Phosphorylation of diacylglycerol kinase in vitro by protein kinase C.
We investigated the effects of enzyme phosphorylation in vitro on the properties of diacylglycerol kinase. Diacylglycerol kinase and protein kinase C, both present as Mr-80,000 proteins, were highly purified from pig thymus cytosol. Protein kinase C phosphorylated diacylglycerol kinase (up to 1 mol of 32P/mol of enzyme) much more actively than did cyclic AMP-dependent protein kinase. Phosphoryl...
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 کاملPhosphorylation of Staphylococcus aureus Protein-Tyrosine Kinase Affects the Function of Glucokinase and Biofilm Formation
Background: When Staphylococcus aureus is grown in the presence of high concentration of external glucose, this sugar is phosphorylated by glucokinase (glkA) to form glucose-6-phosphate. This product subsequently enters into anabolic phase, which favors biofilm formation. The presence of ROK (repressor protein, open reading frame, sugar kinase) motif, phosphate-1 and -2 sites, and tyrosine kina...
متن کاملMultisite phosphorylation of P-Rex1 by protein kinase C
P-Rex proteins are guanine nucleotide exchange factors (GEFs) that act on the Rho/Rac family of GTP binding proteins. The activity of P-Rex proteins is regulated by several extracellular stimuli. In fact, activation of growth factor receptors has been reported to activate a phosphorylation/dephosphorylation cycle of P-Rex1. Such cycle includes dephosphorylation of serines 313 and 319 which nega...
متن کاملMultiple pathways control protein kinase C phosphorylation.
The protein kinase C (PKC) family of signal transducers are characterized by a dependence upon lipids for activity. Specifically, the classical (cPKCα, β and γ) and novel (nPKCδ, ε, η and θ) PKC isotypes display a physiological requirement for diacylglycerol for activity. This property of PKC has defined a now well established signalling pathway operating through receptors to phosphatidylinosit...
