The tyrosine kinase Stitcher activates Grainy head and epidermal wound healing in Drosophila

The wound-healing transcription factor Grainy head upregulates a receptor tyrosine kinase of the Ret-family, Stitcher. Stitcher orchestrates re-epithelialization by triggering rearrangements of the actin cytoskeleton and changes in gene expression through Erk phosphorylation and regulation of Grainy head activity.
