Protein kinases have been found to possess two characteristic conformations in their activation-loops: the active DFG-in conformation and the inactive DFG-out conformation. Recently, it has been very interesting to develop type-II inhibitors which target the DFG-out conformation and are more specific than the type-I inhibitors binding to the active DFG-in conformation. However, solving crystal ...

Many eukaryotic protein kinases are activated by phosphorylation on a specific conserved residue in the regulatory activation loop, a post-translational modification thought to stabilize the active DFG-In state of the catalytic domain. Here we use a battery of spectroscopic methods that track different catalytic elements of the kinase domain to show that the ~100 fold activation of the mitotic ...

background: this study aimed to assess dermis fat graft (dfg) as a choice to correct the tissue deficit in the free border of the upper lip in cleft lip repair surgery. materials and methods: thirty?five individuals who referred to alzahra hospital at 2013–2014,with lip deformity following the primary repair surgery of cleft lip underwent surgery by dfg technique. outcomes were assessed 4 month...
