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 10xHis-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：

Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0

靶點詳情

功能：

This potassium channel is controlled by G proteins. 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 receptor plays a crucial role in regulating the heartbeat.

1. these data suggest that patients with estrogen receptor positive breast cancer might be stratified into high risk and low risk groups based on the KCNJ3 levels in the tumor PMID: 27835900
2. Results clearly corroborate that overexpression of GIRK1 protein exerts profound effects on wound healing, chemoinvasion and cellular motility in the MCF-7 breast cancer cell line suggesting a role to promote invasion and metastasis. PMID: 27519272
3. GIRK1/GIRK4 hetero-tetramers are not activated by Na+, but rather are in a permanent state of high responsiveness to G proteins beta-gamma, suggesting that the GIRK1 subunit functions like a GIRK4 subunit with Na+ permanently bound. PMID: 27074664
4. The findings of this study suggest that variations in KCNJ3 genes are associated with both mild and severe persistent breast pain after breast cancer surgery. PMID: 25599232
5. For KCNJ3 rs7574878, individuals who were heterozygous or homozygous for the rare G allele (TT versus TG+ GG) had a 48% reduction in the odds of reporting preoperative breast pain. PMID: 24392765
6. we show that Kir3.1, in the absence of trafficking partner subunits, can exit the endoplasmic reticulum (ER) and reach the Golgi (though not the plasma membrane) PMID: 23368630
7. In the dorsal horn of the developing rat, K(ir)3.1 and K(ir)3.2 were expressed at mature levels from birth. PMID: 23219908
8. Conformational changes at the Gbetagamma/Kir3 interface were lost when Kir3.1 subunits were replaced. PMID: 23175530
9. These data suggest that the KCNJ3 gene is genetically associated with schizophrenia in Asian populations and add further evidence to the "channelopathy theory of psychiatric illnesses". PMID: 21927946
10. Kir3.1 channel is involved in the TLR4-mediated signal at an early event by facilitating the recruitment of TLR4 into lipid raft. PMID: 21420934
11. halothane predominantly interferes with Gbetagamma-mediated Kir3 currents, such as those functioning during inhibitory synaptic activity PMID: 21044958
12. The very high abundance of mRNA's encoding GIRK1 together with the presence of GIRK1 protein suggests a pathophysiological role in breast cancer PMID: 20512921
13. We identified several known single nucleotide polymorphisms in KCNJ3 and KCNJ5, but no mutations in either of the genes. PMID: 20110696
14. glutamate residue at the C terminus regulates activity -- implications for Andersen Disease (inward rectifier potassium channel 2; IRK2) PMID: 12034888
15. that GIRK channels are important functional effectors of the P2Y(12) receptor in human platelets. PMID: 15142872
16. GIRK1 and GIRK2 channels, but not GIRK3 or GIRK4, may may activate signaling pathways in development of lung cancer PMID: 16109170
17. GIRK1 was overexpressed in breast carcinoma suggesting its involvement in proliferation and oncogenesis and its possible use as a putative pharmaceutical target. PMID: 18498071
18. Sar 1 H79G and Rab 1 S25N mutants efficiently blocked the plasma membrane trafficking of the Kir3.1/Kir3.4 complex however they did not block the Gbeta1gamma2/Kir3.1 interaction. Gbeta1-4 can interact with Kir3.1 in the absence of Kir3.4. PMID: 19135528
19. S385 identified as in vitro phosphorylation site. Mutation of this residue to alanine resulted in reduced sensitivity of Kir3.1* currents to H89 & Forskolin, confirming in vivo role for this novel site of the Kir3.1 channel subunit in regulation by PKA. PMID: 19151997
