Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Arabidopsis thaliana
VDR1, also called Violaxanthin de epoxidase related protein, is a chloroplast thylakoid lumen protein homologous to violaxanthin de epoxidase but often lacks key catalytic residues or shows altered domains, suggesting modified or regulatory function rather than classic xanthophyll cycle activity. It associates with thylakoid membranes and may respond to lumen pH, redox state, and ascorbate availability, contributing to photoprotection and acclimation under high light or stress by modulating pigment interactions or stabilizing protein complexes. VDR1 expression aligns with chloroplast development and light regimes, and perturbation can affect nonphotochemical quenching dynamics, pigment composition, and recovery from photoinhibition. Its precise biochemical role varies by species and remains under investigation, with evidence pointing to supportive or context dependent participation in tuning the xanthophyll cycle and thylakoid organization.
