Abstract excerpt
The two basal bodies of Chlamydomonas are connected by a bridge, the distal fiber, that contains a Ca2+-binding protein, centrin. Although various fibrous structures in many organisms containing centrin or similar proteins have been shown to contract at Ca2+ concentrations >10(-7)-10(-6) M, the contractility of the distal fiber in Chlamydomonas has not been demonstrated. To determine whether it undergoes...
