Occurrence of histone-like tails on RPS6 proteins from lower Diptera

Ribosomal protein S6 (RPS6) is the major phosphorylated protein on the small ribosomal subunit. We have previously shown that cDNAs from the mosquitoes Aedes aegypti, Aedes albopictus and Anopheles stephensi encode a C-terminal extension resembling histone H1 protein. The tail was absent from Drosophila melanogaster and from a member of the Psychodidae. Here we present an analysis of rpS6 cDNAs from representatives of the Chaoboridae and Chironomidae.

Species 1: Diptera Culicidae Aedes albopictus (Asian tiger mosquito)
Species 2: Diptera Culicidae Aedes aegypti (yellow fever mosquito)
Species 3: Diptera Culicidae Anopheles stephensi (malaria mosquito)
Keywords: ribosome, histone
