    Avi-tag Biotinylated

    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

    Tag type will be determined during the manufacturing process.
    The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
  • 产品提供形式：
    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.
  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

  • 功能：
    In the kidney, probably plays a major role in potassium homeostasis. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. This channel is activated by internal ATP and can be blocked by external barium.

    1. ENaC and ROMK channel activity in kidney tubules are inhibited in TgWnk4(pseudoaldosteronism type II) mice. Wnk4(PHAII)-induced inhibition of ENaC and ROMK may contribute to the suppression of K(+) secretion in the tubules. PMID: 28365586
    2. animal knockouts of ROMK1 do not produce Bartter phenotype. ROMK1 is critical in response to high K intake-stimulated K+ secretion in the collecting tubule. PMID: 26728465
    3. Lovastatin stimulates ROMK1 channels by inducing PI(4,5)P2 synthesis, suggesting that the drug could reduce cyclosporine-induced nephropathy. PMID: 25349201
    4. It was concluded that miR-194 regulates ROMK channel activity by modulating ITSN1 expression thereby enhancing ITSN1/WNK-dependent endocytosis. PMID: 24197061
    5. hypertension resistance sequence variants inhibit ROMK channel function by different mechanisms PMID: 20926634
    6. knockout mice have impaired renal NaCl absorption; a model for type II Bartter's syndrome PMID: 12122007
    7. Absence of small conductance K+ channel (SK) activity in apical membranes of thick ascending limb and cortical collecting duct in knockout mice a model for bartter's disease__ PMID: 12130653
    8. ROMK is required for functional expression of the 70-pS K channel in the thick ascending limb. PMID: 14600033
    9. mutant WNK4 does not have a dominant effect on the cellular localization of kidney ROMK PMID: 15907795
    10. The expression of ROMK channels in the plasma membrane is regulated by PTK, SGK, and with-no-lysine-kinase 4. A recent study indicated that ROMK channels can be monoubiquitinated and monoubiquitination regulates the surface expression of ROMK channels. PMID: 16339961
    11. Potassium absorption in the loop of Henle is reduced in Romk-deficient mice and can account for a significant fraction of renal potassium loss. PMID: 16710355
    12. mRNA expression of ROMK is augmented in the renal medullary tubule by NaCl-induced hypertonicity through stimulation of ROMK gene transcription, and that TonEBP and the p38 MAPK and ERK pathways are involved in this effect. PMID: 17003571
    13. Potassium restriction suppresses the expression of PP2B catalytic subunits and that inhibition of PP2B decreases ROMK channel activity. PMID: 18184875
    14. adaptive changes in Romk(-/-) mice may help to limit renal Na(+) loss PMID: 18322017
    15. absolute excretion of Na(+) and K(+) were significantly blunted in Romk(-/-) mice, consistent with a major salt transport defect in the thick ascending limb PMID: 18385266
    16. more severe Bartter phenotype in female ROMK null mice, and higher PGE(2) and TXB(2) production may be one of the mechanisms of this manifestation PMID: 18579648
    17. KS-WNK1 is an important physiological regulator of renal K(+) excretion, likely through its effects on the ROMK1 channel. PMID: 19244242
    18. cortical collecting duct cells demonstrate a significant K(+) secretion, probably mediated by ROMK, which is not stimulated by aldosterone but increased by overnight exposure to a high K(+) concentration PMID: 19297448
    19. We propose that in taste buds, ROMK in type I/glial-like cells may serve a homeostatic function, excreting excess K(+) through the apical pore, and allowing excitable taste cells to maintain a hyperpolarized resting membrane potential. PMID: 19708028
    20. ARH marks ROMK for clathrin-dependent endocytosis, in concert with the demands of potassium homeostasis PMID: 19841541
