Clustalx alignment of poly with putative homologues. Drosophila melanogaster poly is virtually identical to homologues in other drosophilids and displays moderate sequence homology to those in other insect species; it diverges most greatly from mammalian homologues. each protein sequence is labeled by genus and species and the name of the protein; for drosophilids, the genus is denoted as D and the first three letters of the species name are added. In the alignment, the bar graph under each amino acid delineates the conservation of that amino acid in the alignment of all protein sequences.
