A chimeric construct in which the tin homeodomain has been replaced by the Mmus\Nkx2-5 homeodomain and NK2-specific domain is expressed under the control of an Hsp70 promoter.
tin::Mmus\Nkx2-52.5HD-NK2SD.hs is a suppressor of larval pericardial cell phenotype of tinEC40
Restores the formation of pericardial cells when expressed in tinEC40 embryos at 3.5 to 4.5 hours of development, although the cells are in a disorganised pattern.
Assayed in D.melanogaster.
