Residual Su(var)3-9 ORF in the eIF2γ intron 81-1 of pea aphids. This reading frame is located between nucleotide 2138 and 2251 of the 2539-nt-intron in the same orientation as the surrounding eIF2γ ORF. The lower sequence is a consensus of 38 Su(var)3-9 proteins in the corresponding region SET-C. Positions are given according to D. melanogaster Su(var)3-9. Identical and similar amino acids are marked. Residues found identically in the majority of Su(var)3-9 proteins are boxed grey.
