Substitution of GDDG for GRQG in the Imp KH1 RNA-binding domain. Induced on the P{PTT-un}G00080 chromosome; the inserted protein trap element is still present.
GATGAC
The substitution of 6 nucleotides (CGACAG to GATGAC) results in the substitution of GDDG for GRQG in the Imp KH1 RNA-binding domain.
