ATH3 — Brassica oleracea

Summary

BoATH3 (BOLC102_C09P026530.1) on cabbage chromosome 9 encodes a thioredoxin H-type protein with oxidoreductase activity acting on sulfur-group donors, protein-disulfide reductase activity, enzyme inhibitor activity, mRNA binding, and protein binding. The gene is associated with responses to microbial phytotoxin, hydrogen peroxide, oxidative stress, heat, cold, and heat acclimation, as well as protein folding, protein oligomerization, pollen recognition, and plasmodesma-mediated cell-to-cell transport. It is linked to self-incompatibility and heterosis traits. The encoded protein localizes to the plant-type cell wall, vacuole, chloroplast stroma, plastid, plasmodesma, Golgi, mitochondria, cytosol, and plasmalemma. Related genes in other species are associated with hydrogen peroxide tolerance, cell cycle regulation, methionine sulfoxide assimilation, oxidative stress tolerance, and abscisic acid signaling.
