translation elongation factor EF-1 alpha, eEF1A, EF-1 alpha, L000002278, YBR118W
Translational elongation factor EF-1 alpha; also encoded by TEF1; functions in the binding reaction of aminoacyl-tRNA (AA-tRNA) to ribosomes; TEF2-RFP levels increase during replicative aging; may also have a role in tRNA re-export from the nucleus; TEF2 has a paralog, TEF1, that arose from the whole genome duplication

Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Publication

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]
