Genetic

YNL064C is suppressed by FES1


Strain Background: W303 (see detailed notes from Rodney Rothstein and Stephan Bartsch for the W303 strain used in the study)
Mutation type(s): point mutation (ydj1-151), deletion

The thermosensitivity and cycloheximide sensitivity of the single deltafes1 and ydj1-151 mutants is partly suppressed in the double mutant. [7] [8]
