Highly conserved protein kinases involved in the regulation of carbon and amino acid metabolism
J Exp Bot.

Abstract
It has been clear for over a decade and a half that ancient signalling pathways controlling fundamental cellular processes are highly conserved throughout the eukaryotes. Two plant protein kinases, sucrose non-fermenting 1 (SNF1)-related protein kinase (SnRK1) and general control non-derepressible 2 (GCN2)-related protein kinase are reviewed here. These protein kinases show an extraordinary level of conservation with their fungal and animal homologues given the span of time since they diverged from them. However, close examination of the signalling pathways in which they operate also reveals intriguing differences in activation and function.
