We characterized a nuclear gene and its corresponding cDNA encoding β-tubulin (gene TubB1) of the marine red alga Chondrus crispus. The deduced TubB1 protein is the most divergent β-tubulin so far reported with only 64 to 69% amino acid identity relative to other β-tubulins from higher and lower eukaryotes. Our analysis reveals that TubB1 has an accelerated evolutionary rate probably due to a release of functional constraints in connexion with a specialization of microtubular structures in… CONTINUE READING
