Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標簽：

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：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
復溶：

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
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：

3-7 business days
注意事項：

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

靶點詳情

功能：

Regulatory subunit of lactose synthase, changes the substrate specificity of galactosyltransferase in the mammary gland making glucose a good acceptor substrate for this enzyme. This enables LS to synthesize lactose, the major carbohydrate component of milk. In other tissues, galactosyltransferase transfers galactose onto the N-acetylglucosamine of the oligosaccharide chains in glycoproteins.
基因功能參考文獻：
1. This study shows, for the first time, that alpha-lactalbumin isolated in a rare 28kDa dimeric form induces cell death, while 14kDa monomeric alpha-lactalbumin is inactive. PMID: 28193539
2. Macromolecular crowding reduces the calcium binding affinity of holo-lactalbumin alpha resulting in the formation of apo-lactalbumin alpha (the calcium-depleted form of holo-LA) leading to aggregate formation. PMID: 25437004
3. Data suggest that stabilization of apo-alpha-lactalbumin by mono- and oligo-saccharides can be accounted for by simplified statistical-thermodynamic model considering volume exclusion deriving from steric repulsion between protein and saccharides. PMID: 26000826
4. These findings suggest that the SNP alpha-LA2516 in the alpha-LA gene likely does not have potential as a molecular marker for milk production traits in Chinese Holstein cows. PMID: 24065678
5. alphaLA forms a misfolded disulfide bond shuffled isomer, X-alphaLA which represents a different low energy fold for the protein; binding calcium plays an important role in both maintaining the native structure of alphaLA and providing a mechanism for distinguishing between folded and misfolded species. PMID: 22189830
6. Structural features of the alphaB-crystallin oligomer when complexed with target proteins under mild stress conditions, i.e., reduction of alpha-lactalbumin at 37 degrees C and malate dehydrogenase when heated at 42 degrees C, were investigated. PMID: 21152271
7. the organization and dynamics of the functionally important tryptophan residues of BLA in native, molten globule and denatured states utilizing the wavelength-selective fluorescence approach were explored. PMID: 20346348
8. The complexes formed by partially folded alpha-lactalbumin with oleic acid display selective apoptotic activity against tumor cells. PMID: 19968717
9. a functional Ca(2+)-binding site is not required for conversion of alpha-lactalbumin to the active complex or to cause cell death PMID: 14627739
10. Negatively charged alpha-lactalbumin (LA) interaction with basic histone stabilizes apo-alpha-LA and destabilizes the Ca2+-bound protein due to compensation for excess negative charge of alpha-LA's Ca2+-binding loop by positively charged histone residues. PMID: 15134431
11. interaction of alphaB-cyrstallin with, and promoted unfolding of, reduced alpha-lactalbumin, but showed limited chaperone activity for other target proteins PMID: 15670152
12. Data indicate that deletion of the beta-subdomain in alpha-lactalbumin does not alter the ability of the protein to assemble into well-ordered fibrils, implying that this chain region is not essential for the amyloid formation. PMID: 15853802
13. Fold and topology of alpha-lactalbumin may be formed from degenerate groups of side chains. PMID: 15956205
14. residual long-range interactions may act as nucleation sites for protein folding, while this property of residual structure is replaced by the calcium-binding site between the domains in alpha-lactalbumin. PMID: 16731974
15. characterized the acid induced molten globule state (A-state) of alpha-LA both qualitatively and quantitatively. PMID: 16741984
16. Results describe the reaction mechanism and formation of CIDNP (chemically induced dynamic nuclear polarization) in the photoreactions of the dye 2,2'-dipyridyl with non-native states of bovine and human alpha-lactalbumins in aqueous solution. PMID: 16851644
17. interaction between calcium-depleted alpha-lactalbumin and lysozyme leads to the formation of different supramolecular structures depending on the temperature PMID: 17260954
18. stopped-flow CD, fluorescence, and time-resolved NMR studies that the Ca(2+)-induced refolding of bovine alpha-lactalbumin (BLA) at constant denaturant concentration (4 M urea) exhibits triple-exponential kinetics. PMID: 18377934
19. Allelic frequencies and RFLP patterns of alpha-lactalbumin gene vary between two species of cattle. PMID: 18607792
20. Disulfide bond shuffling in bovine alpha-lactalbumin: MD simulation confirms experiment PMID: 18942855
