SAT — Brassica juncea

Summary

BJUB02G25180S (SAT) on chromosome B02 of Indian mustard (Brassica juncea) encodes a protein containing a PI3K-type C2 domain and a C2 domain superfamily fold, with annotated vinorine synthase and acyltransferase activities and ATP binding. The gene is associated with phosphatidylinositol 3-kinase complexes, pexophagy, PI(3)P biosynthesis, phosphoinositide-mediated signaling, endocytosis, electron transport chain, glutathione metabolism, and alkaloid metabolism. It localises to membranes, cytoplasm, nucleus, endosomes, and peroxisomes. Associations with agronomic traits include sulfur content, photosynthetic ability, transpiration rate, stomatal resistance, ethylene sensitivity, chlorophyll content, and photochemical quenching. Studies of related genes in other species link the family to additional acyltransferase and kinase activities (EC 2.3.1.160, 2.3.1.323, 2.7.1.137).
