the 50 sequences , belonging to seven protein lineages related by gene duplication ( calmodulin itself , troponin-c , alkali and regulatory light chains of myosin , parvalbumin , intestinal calcium-binding protein , and glial s-100 phenylalanine-rich protein ) , came from a wide range of eukaryotic taxa and yielded a denser tree ( more branch points within each lineage ) than in earlier studies .
