摘要: Eukaryotic Protein Kinases (ePKs) are essential for eukaryotic cell signalling. Several phylogenetic trees of the ePK repertoire single eukaryotes have been published, including human kinome tree. However, a eukaryote-wide tree was missing due to large number kinases in eukaryotes. Using pipeline that overcomes this problem, we present here first The reveals Last Common Ancestor (LECA) possessed at least 92 ePKs, much more than previously thought. retention these LECA ePKs present-day species is highly variable. Fourteen with unresolved placement were found originate from three known superfamilies. Further analysis superfamilies shows they exhibit markedly diverse evolutionary dynamics between and thus unveils history but also enables transfer functional information related kinases.
