Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Genetic interactions between a null allele of the RIT1 gene encoding an initiator tRNA-specific modification enzyme and genes encoding translation factors in Saccharomyces cerevisiae.

The Saccharomyces cerevisiae gene RIT1 encodes a phospho-ribosyl transferase that exclusively modifies the initiator tRNA (tRNAMet(i)) by the addition of a 2'-O-ribosyl phosphate group to Adenosine 64. As a result, tRNAMet(i) is prevented from participating in the elongation steps of protein synthesis. We previously showed that the modification is not essential for the function of tRNAMet(i) in the initiation of ... [more]
