CC-1370 fa1 mt+

From Ralph Lewin, Scripps Institution of Oceanography, October 1982

Phenotype: impaired flagellar autotomy

The fa1 mutant was isolated by Lewin and Burrascano after UV mutagenesis, and characterized as a mutant that does not shed its flagella under conditions such as pH shock, treatment with ethanol, etc. Further analysis by Finst et al. showed that the defect is specifically in severing outer doublets of the microtubules in response to calcium, and that the corresponding gene is a novel 171-kD protein.
