TIF1

translation initiation factor eIF4A, eIF4A, L000002302, YKR059W
Translation initiation factor eIF4A; DEA(D/H)-box RNA helicase that couples ATPase activity to RNA binding and unwinding; forms a dumbbell structure of two compact domains connected by a linker; interacts with eIF4G; protein abundance increases in response to DNA replication stress; TIF1 has a paralog, TIF2, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

A yeast model for polyalanine-expansion aggregation and toxicity.

Konopka CA, Locke MN, Gallagher PS, Pham N, Hart MP, Walker CJ, Gitler AD, Gardner RG

Nine human disorders result from the toxic accumulation and aggregation of proteins with expansions in their endogenous polyalanine (polyA) tracts. Given the prevalence of polyA tracts in eukaryotic proteomes, we wanted to understand the generality of polyA-expansion cytotoxicity by using yeast as a model organism. In our initial case, we expanded the polyA tract within the native yeast poly(Ade)-binding protein ... [more]
