Negative regulation of Raf-1 by phosphorylation of serine 621.
The elevation of cyclic AMP (cAMP) levels in the cell downregulates the activity of the Raf-1 kinase. It has been suggested that this effect is due to the activation of cAMP-dependent protein kinase (PKA), which can directly phosphorylate Raf-1 in vitro. In this study, we confirmed this hypothesis by coexpressing Raf-1 with the constitutively active catalytic subunit of PKA, which could fully r...

Phosphorylation 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...

Regulation of the Raf-1 kinase domain by phosphorylation and 14-3-3 association.
The Raf-1 kinase domain is kept in an inactive state by the N-terminal regulatory domain. Activation of the kinase domain occurs following release from the N-terminal repression and possible catalytic upregulation. To distinguish the regulatory mechanisms that directly influence the catalytic activity of the enzyme from those which act through the inhibitory domain, the catalytic domain of Raf-...
