SpCBFβ does not contribute to the anti-apoptotic function of SpRunt-1. (A) Gastrula stage SpRunt-1 morphant fluorescently imaged with TUNEL (green, indicating apoptosis) and DAPI (blue, indicating DNA). (B) Gastrula stage SpCBFβ morphant fluorescently imaged with TUNEL and DAPI as in (A). (C) EMSA of recombinant wild-type and mutant (G115R) Runt domain (α) from SpRunt-1, in the presence or absence of recombinant SpCBFβ. Note that while the G115R mutant Runt domain binds DNA, it does not heterodimerize with SpCBFβ. (D) Gastrula stage SpRunt-1 morphant that has been co-injected with full-length mRNA encoding SpRunt-1-G115R, fluorescently imaged with TUNEL and DAPI as in (A). Note that while cell survival is rescued, as indicated by a lack of TUNEL signal, other aspects of development such as skeletogenesis are not.
