Construction details
p5E-UAS was made by conventionally subcloning into p5E-MCS a HindIII-EcoRI fragment from a UAS-E1b construct from Reinhard Köster, containing multimerized Gal4 upstream activating sequence (UAS) elements, followed by what is presumably a carp beta-actin minimal promoter and then by a piece of the carp beta-actin 5' UTR.
While the source construct nominally contained a 14x UAS element (originally made by Pernilla Rorth), sequencing shows that p5E-UAS only contains 10x UAS elements. Presumably there was an internal rearrangement that shed 4 UAS elements; it is not clear whether had already happened in the UAS-E1b construct, or whether it occurred in the Chien lab.
Functional tests of constructs using this element show strong activation by Gal4.
