Clustering Drosophila proteins. Drosophila proteins were clustered into paralogous groups based on their sequence similarity. Using methods described in the text, 1850 groups of Drosophila specific proteins make up 18% of fruitfly paralogous groups, and 1346 (13%) insect core proteins were identified. In the insect core set, 466 groups (5%) can be found in other eukaryotes, and 154 groups (1%) are insect specific.
