Response to Comment on Ancient origins of allosteric activation in a Ser-Thr kinase

Park et al. question one out of seven findings from Hadzipasic et al.: whether TPX2 allosterically regulates the oldest Aurora. We had already addressed the two concerns raised-sparse sequence sampling and not forcing the gene to the species tree-before publication. Moreover, we believe their ancestral sequence reconstruction would be consistent with a nonallosteric common ancestor, and we show large sequence differences caused by species tree-enforced gene trees.
