PsbS/22 kDa Lhc-like PSII protein Antibody (AS03-032) in WB
15 µg of Arabidopsis thaliana thylakoids from (1) Psb S-overexpressing line, (2) Psb S-deficient npq 4-line, and (3) wt (col) together with (4) total leaf protein from Arabidopsis thaliana wt extracted with PEB, AS08 300, were separated on 4-12% Nu PAGE(Invitrogen) LDS-PAGE and blotted 1 h to nitrocellulose. Filters were blocked 1 h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-P... View More

靶标信息
PSBS encodes a small thylakoid membrane protein essential for activating non photochemical quenching (NPQ) in plants, the rapid photoprotective process that dissipates excess excitation energy as heat to prevent damage under high or fluctuating light. Unlike pigment-binding LHCB proteins, PsbS does not bind chlorophyll; instead, it senses lumenal pH changes via protonatable residues and triggers conformational shifts in the light-harvesting antenna that enable energy dissipation. PsbS is localized to the grana regions of chloroplast thylakoids and functions as a central regulator of the qE component of NPQ, working in concert with the xanthophyll cycle (violaxanthin/zeaxanthin interconversion) and LHCII. Its expression is light inducible and stress-responsive, and genetic manipulation of PSBS alters photoprotection capacity, influencing photosystem II stability, carbon fixation efficiency, and plant productivity, particularly under dynamic light environments.
