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 200 µL of sterile water.
Specific Species Reactivity: Coccomyxa subellipsoidea, Ostreococcus tauri
LHCB4 encodes a nuclear-encoded, chloroplast-targeted light-harvesting chlorophyll a/b-binding antenna polypeptide that accumulates in the thylakoid membrane as a minor photosystem II (PSII) antenna component, commonly referred to as CP29, positioned at the interface between the PSII core and peripheral LHCII antenna to help organize PSII supercomplex architecture. The mature protein is an integral membrane Lhc family member built on a conserved fold with multiple transmembrane alpha-helices (classically three) that create pigment-binding pockets coordinating chlorophylls and carotenoids, enabling efficient absorption of light and rapid excitation-energy transfer toward the PSII reaction center. Genetic analyses in Arabidopsis show that loss of all LHCB4 isoforms preserves gross electron transport capacity but disrupts PSII macro-organization, accelerates state-transition kinetics, reduces nonphotochemical quenching capacity, and increases sensitivity to photoinhibition, supporting a key role for LHCB4 in stabilizing PSII-LHCII interactions and in photoprotective energy dissipation under excess light.
