Required for embryonic epithelial tissue repair, but not for the assembly of the actomyosin cable at the wound edge. Probably acts downstream of rl in the regulation of Ddc and msn transcription to promote wound healing. Expressed maternally and zygotically. Expression is ubiquitous throughout embryonic development. Embryonic lethal. Embryonic wound healing defects. The few adult escapers show subtle rough eye phenotype and extra and/or misplaced or missing macrochaetae on the scutellum.
