| ORF Classification | Verified |
| Description | Thioredoxin peroxidase; acts as both a ribosome-associated and free cytoplasmic antioxidant; self-associates to form a high-molecular weight chaperone complex under oxidative stress; deletion results in mutator phenotype; protein abundance increases and forms cytoplasmic foci in response to DNA replication stress; required for telomere length maintenace; TSA1 has a paralog, TSA2, that arose from the whole genome duplication (10, 11, 2, 3, 4, 5, 6, 7, 8, 9) |
