involved in abscisic acid-mediated response to osmotic stress
Title: Thylakoid membrane oxidoreductase LTO1/AtVKOR is involved in ABA-mediated response to osmotic stress in Arabidopsis.

The conserved cysteines in the AtVKOR domain also played critical roles in phylloquinone reduction. When each of the four conserved cysteines was mutated to alanine, the mutants lost reduction activity entirely.
Title: Key amino acids of arabidopsis VKOR in the activity of phylloquinone reduction and disulfide bond formation.

LTO1 is involved in the xanthophyll cycle and the acceleration of D1 protein degradation.
Title: The chloroplast protein LTO1/AtVKOR is involved in the xanthophyll cycle and the acceleration of D1 protein degradation.

Results identified HCF164 as a direct target of LTO1 interacting with its thioredoxin-like domain suggesting that VKOR may play an important role in regulating the redox state of proteins in the thylakoid lume.
Title: Identification of potential targets for thylakoid oxidoreductase AtVKOR/LTO1 in chloroplasts.

LTO1 plays important roles in redox regulation, ROS homeostasis and maintenance of PSII.
Title: A chloroplast membrane protein LTO1/AtVKOR involving in redox regulation and ROS homeostasis.
