Dpp binding is important for the function of Tkv. (A and B) The overexpression of Tkv[EX]-GFP in the ECs of a tkvi (v105834) germarium suppresses the formation of ectopic spectrosome-containing cells. (C and D) The expression of Tkv[EX]-Flag in ECs mutant (C, arrowheads) for the tkv8 allele partially suppresses the formation of ectopic spectrosome-containing cells.
