How can a constitutively active 'master' kinase with numerous downstream targets preferentially phosphorylate one or more of these without influencing all simultaneously? How might such a system be switched off? The characterization of the role of deubiquitination in regulating the phosphorylation and activation of AMPK (AMP-activated protein kinase)-related kinases by LKB1 suggests a novel and interesting mechanism for conferring signal transduction specificity and control at the kinase… CONTINUE READING
