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：

N-terminal 6xHis-tagged
產品提供形式：

Liquid or Lyophilized powder
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.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
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°C for up to one week.

功能：

Exhibits phosphohistidine phosphatase activity.
基因功能參考文獻：
1. In the process of assay optimization, we discovered that PHPT1 is sensitive to a reducing environment and inhibited by transition-metal ions, with one apparent Cu(II) binding site with IC50 value of 500 +/- 20 muM and two apparent Zn(II) binding sites with IC50 values of 25 +/- 1 and 490 +/- 20 muM PMID: 29630837
2. High PHPT1 expression is associated with cancer. PMID: 29787434
3. H2O2 exposure induces selective oxidation of hPHPT1 at Met95, a residue within the substrate binding region. Molecular dynamics simulations suggest that if Met95 oxidation alters hPHPT1 activity, then it will do so by altering the stability of an intermediate state. Mass spectrometry showed that H2O2-induced oxidation does not impact hPHPT1 function negatively. PMID: 27034094
4. PHPT1 was expressed in the epithelium of proximal tubuli and nuclei of clear-cell renal cell carcinoma tissue samples. PMID: 26537769
5. PHPT1 can dephosphorylate phospholysine in chemically phosphorylated histone H1 and polylysine PMID: 25574816
6. The specific degradation of the PHPT1 splice variant indicates that the quality control and the self-guarding of the cellular system works at two levels, first at the RNA level and proteasome level. PMID: 25450458
7. the histidine phosphatase, protein histidine phosphatase 1, inhibits NDPK-B-activated TRPV5 in inside/out patch experiments. PMID: 24523290
8. Overexpression of PHP by the use of a plasmid vector, pIRES2-AcGFP1-PHP, induced apoptosis in HUVEC PMID: 21967643
9. Significantly higher expression levels of PHPT1 protein were found in lung cancer samples than in normal tissues adjacent to lung cancer. PMID: 21163124
10. these data implicate regulatory roles for PHPT1 in a G protein-sensitive step involved in nutrient-induced insulin secretion PMID: 20501872
11. These results demonstrate for the first time that PHP14 may be functionally important in lung cancer cell migration and the invasion of lung cancer cells, mediated partly through modulation of actin cytoskeleton rearrangement. PMID: 19344975
12. Northern blot analysis indicated that the human phosphohistidine phosphatase mRNA was present preferentially in heart and skeletal muscle. PMID: 12383260
13. In the present work, we have searched for potential active site residues in the human phosphohistidine phosphatase by point mutations of conserved histidine and arginine residues to alanine. PMID: 16219293
14. Overexpression of PHP results in increased dephosphorylation with concomitant inactivation of ACL, thus finally leading to cell damage. PMID: 18656514
15. PHPT-1 functions to negatively regulate CD4 T cells PMID: 18796614
16. Solution structure and catalytic mechanism of human protein histidine phosphatase 1. PMID: 18991813
17. results suggest that an increased activity of protein histidine phosphatase (PHP) impairs neuron cellular function whereas downregulation of PHP does not PMID: 19138678
