TSA1

TPX1, ZRG14, thioredoxin peroxidase TSA1, cTPxI, L000002365, YML028W
Thioredoxin peroxidase; acts as both ribosome-associated and free cytoplasmic antioxidant; self-associates to form high-molecular weight chaperone complex under oxidative stress; chaperone activity essential for growth in zinc deficiency; required for telomere length maintenance; protein abundance increases, forms cytoplasmic foci during DNA replication stress; TSA1 has a paralog, TSA2, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)
PREY

TSA2

thioredoxin peroxidase TSA2, cTPxII, YDR453C
Stress inducible cytoplasmic thioredoxin peroxidase; cooperates with Tsa1p in the removal of reactive oxygen, nitrogen and sulfur species using thioredoxin as hydrogen donor; deletion enhances the mutator phenotype of tsa1 mutants; protein abundance increases in response to DNA replication stress; TSA2 has a paralog, TSA1, that arose from the whole genome duplication

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Ribosome-associated peroxiredoxins suppress oxidative stress-induced de novo formation of the [PSI+] prion in yeast.

Sideri TC, Stojanovski K, Tuite MF, Grant CM

Peroxiredoxins (Prxs) are ubiquitous antioxidants that protect cells against oxidative stress. We show that the yeast Tsa1/Tsa2 Prxs colocalize to ribosomes and function to protect the Sup35 translation termination factor against oxidative stress-induced formation of its heritable [PSI(+)] prion conformation. In a tsa1 tsa2 [psi(-)] [PIN(+)] strain, the frequency of [PSI(+)] de novo formation is significantly elevated. The Tsa1/Tsa2 Prxs, ... [more]
