Substitution of GDDG for GKSG in the Imp KH2 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 (AAGTCG to GATGAC) results in the substitution of GDDG for GKSG in the Imp KH2 RNA-binding domain.
