Fig. 6.

Aphids possess IAPs with more than three BIR domains and one RING domain. The domain composition of IAP proteins from 11 available aphid genomes and Daktulosphaira vitifoliae is shown. The number of protein-encoding genes relative to each IAP domain composition in each species is indicated. Aphid IAPs present an important structural diversity with one to five BIR domains and one to three RING domains. The BIR domains are represented by a red rectangle, the RING domains by a green oval, and the UBA domain by a pink oval. The structures are not represented to scale.
