abstract：:Paxbeta is a novel gene family restricted to the bilaterian superphylum Lophotrochozoa. The Paxbeta paired domain is highly diverged from other bilaterian Pax genes, and we were unable to identify an unambiguous sister-group by phylogenetic sequence analysis. However, conservation of a paired domain intron suggests th...

Previous studies find a highly stringent structure/function relationship between the Drosophila melanogaster testis-specific tubulin beta2 and the spermtail axoneme, such that small changes in the beta2 protein render it unable to generate a motile axoneme. This...
