Creolimax fragrantissima is a member of the ichthyosporean clade, the earliest branching holozoan lineage. The kinome of Creolimax is markedly reduced as compared to those of metazoans. In particular, Creolimax possesses a single non-receptor tyrosine kinase: CfrSrc, the homolog of c-Src kinase. CfrSrc is an active tyrosine kinase, and it is expressed throughout the lifecycle of Creolimax. In animal cells, the regulatory mechanism for Src involves tyrosine phosphorylation at a C-terminal site by Csk kinase. The lack of Csk in Creolimax suggests that a different mode of negative regulation must exist for CfrSrc. We demonstrate that CfrPTP-3, one of the 7 tyrosine-specific phosphatases (PTPs) in Creol...
