The honey bee genome contains three knirps-related genes. (A) Amino acids sequence comparison of the Zn finger domain from Knirps-related proteins including those predicted from the honey bee genome sequence. Asterisks indicate residues that are conserved in kni but not egon proteins; (Dp) Drosophila pseudoobscura. (B) Phylogenetic analysis of the Cys–Cys finger domains from Knirps-related proteins. kni from D. melanogaster forms a clade with kni proteins from other Drosophila species. (C) Genomic location of honey bee knirps-related genes. The three predicted knirps-related genes (knr1, knr2, and knr3) are clustered on Baylor scaffold group 10.
