A PI4KIIIα rescue transgene generated as a genomic-cDNA fusion: the 5' half conisting of genomic DNA encoding PI4KIIIα is joined to the 3' half containing cDNA from clone SD12145.
Pi4KIIIα+tTa rescues Pi4KIIIαC
Pi4KIIIα+tTa rescues Pi4KIIIαΔ123
PI4KIIIα+tTa fully rescues PI4KIIIαΔ123 mutants to viability, and rescues the ring canal phenotype seen in PI4KIIIαΔ123 germline clones.
