TRX1/YLR043C Protein Information Help

Standard Name Trx1p
Systematic Name Ylr043cp
Alias Lma1p 1
ORF Classification Verified
Description Cytoplasmic thioredoxin isoenzyme; part of thioredoxin system which protects cells against oxidative and reductive stress; forms LMA1 complex with Pbi2p; acts as a cofactor for Tsa1p; required for ER-Golgi transport and vacuole inheritance; with Trx2p, facilitates mitochondrial import of small Tims Tim9p, Tim10p, Tim13p by maintaining them in reduced form; abundance increases iunder DNA replication stress; TRX1 has a paralog, TRX2, that arose from the whole genome duplication (1, 10, 2, 3, 4, 5, 6, 7, 8, 9)
