Medical Definition of Caltractin
1.
Calcium binding (EF hand) protein (20 kD) from Chlamydomonas reinhardtii. Major component of the contractile striated rootlet system that links basal bodies to the nucleus in Chlamydomonas. Part of the calmodulin / troponin C family, it has sequence homology with 20 kD calcium-binding proteins (centrins) found in other basal body associated structures and with the cdc31 gene product associated with spindle pole body duplication in the yeast Saccharomyces cerevisiae.
