Genetic

YDL120W is suppressed by RAS2


Strain Background: W303-1B (see detailed notes from Rodney Rothstein and Stephan Bartsch for the W303 strain used in the study)
Mutation type(s): deletion, partial deletion

A mutation in RAS2 supressed a growth defect of deltaYFH1 strain on toxic levels of iron in growth media. [11] [12]
