產品提供形式：

Liquid or Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Plays an important role in non-photochemical quenching, a process maintains the balance between dissipation and utilization of light energy to minimize generation of oxidizing molecules, thereby protecting the plant against photo-oxidative damage. Is not necessary for efficient light harvesting and photosynthesis.
基因功能參考文獻：
1. The interaction of PsbS with the antenna system is affected by both DeltapH and the level of zeaxanthin. PMID: 28134919
2. the importance of LHCII aggregation in the NPQ mechanism PMID: 26233261
3. Npq1 and npq4 mutants are equally protected against photodamage, but less protected than WT plants. PMID: 25429003
4. It was concluded that functional PsbS is required for optimization of absorbed photon fate and optimal light acclimatory responses. PMID: 25654166
5. Leaves from three different Arabidopsis lines with different expression levels of PsbS protein showed different levels of non-photochemical quenching. The PsbS deficient plant npq4 showed remarkable reduction of electron transport rate. PMID: 25047739
6. the presence of violaxanthin deepoxidase, but not the protein PsbS, changes the excited-state relaxation dynamics of chlorophyll; the presence of both zeaxanthin and PsbS is required for strong quenching PMID: 25422428
7. Changes in the complement of light-harvesting complexes and PsbS have striking effects on the photosystem II macrostructure, and these effects correlate with changes in the mobility of chlorophyll proteins within the thylakoid membrane. PMID: 21919982
8. Direct interaction of the major light-harvesting complex II and PsbS in nonphotochemical quenching. PMID: 23509270
9. Restoration of rapidly reversible photoprotective energy dissipation in the absence of PsbS protein by enhanced DeltapH. PMID: 21474447
10. Data suggest that PsbS plays the role of a kinetic modulator of the energy dissipation process in the PSII light-harvesting antenna. PMID: 19843315
11. Data suggest that PsbS controls the macro-organisation of the grana membrane, providing an explanation of its role in NPQ. PMID: 20035752
12. The effects of two different mutations of PsbS on the metabolism of photosystem II in A. thaliana are reported. PMID: 16075321
13. Binding of two molecules of zeaxanthin in the three-dimensional model of PsbS is postulated. The molecular mechanism of photoprotection by PsbS is explained through the model. PMID: 16538483
14. PsbS acts as a trigger of the conformational change that leads to the establishment of nonphotochemical quenching. PMID: 16545380
15. Transgenic Arabidopsis lines synthesizing only the altered psbS forms exhibited severely impaired NPQ capacity PMID: 17306227
16. xanthophyll dependence of energy dissipation is not due to PsbS but to other pigment-binding proteins, probably of the Lhcb type PMID: 18070876
17. The level of PsbS is a determinant of plant fitness, metabolism and gene expression. Lack of PsbS results in increased photooxidative stress in the chloroplasts. PMID: 19171025
