A 0.5kb genomic fragment containing the region upstream of the Caf1 start codon followed by the full-length coding region.
Caf1-55t0.5p55 fails to rescue Caf1-55p55-2/Caf1-55p55-1
Expression of Caf1t0.5p55 is unable to rescue the lethality and developmental delay phenotypes seen in Caf1p55-1/Caf1p55-2 mutants.
