TABLE 2.
Summary of EST1 RRM mutants
EST1 allele | Phenotypea
|
||
---|---|---|---|
Viability | Tlc1 RNA binding | Telomere length | |
Wild type | +++ | +++ | +++ |
RNP1-NC | −−− | −−− | −−− |
RNP1-C | +++ | ++ | ++ |
RNP2-ga | +++ | +++ | +++ |
RNP2-gs | +++ | + | + |
+++, wild-type behavior; ++ or +, EST1 activity slightly or considerably less than wild-type activity, respectively; −−−, no EST1 activity (i.e., no complementation of an est1 mutant).
