Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. Additionally we are shipping KCNJ2 Antibodies (94) and KCNJ2 Proteins (5) and many more products for this protein.
We report a novel KCNJ2 sequence variant (p.Y145C) in a family with diagnosed Andersen-Tawil syndrome.
Combined inhibition of IKr and IKur produced a synergistic anti-arrhythmic effect in both forms of SQT3. In conclusion, this study provides mechanistic insights into atrial proarrhythmia with SQT3 Kir2.1 mutations and highlights possible pharmacological strategies for management of SQT3-linked AF.
Data suggest that an R204A mutation disrupts the characteristic cytoplasmic domain subunit interface salt bridges in Kir2.1 reducing apparent sensitivity of channel activity to ligand PIP2 (phosphatidylinositol bisphosphate).
These findings suggest that KCNJ2 plays an important role in the pathophysiology of Thyrotoxic Periodic Paralysis in Korean Graves' Disease patients with Thyrotoxic Periodic Paralysis .
Nav1.5 (show SCN5A ELISA Kits) N-terminal domain binding to alpha1-syntrophin (show SNTA1 ELISA Kits) increases membrane density of human Kir2.1, Kir2.2 (show KCNJ12 ELISA Kits) and Nav1.5 (show SCN5A ELISA Kits) channels
Kir2.1 may participate in macrophage maturation and differentiation, and play a key role in lipid uptake and foam cell formation through modulating the expression of scavenger receptors.
a Korean family with Andersen-Tawil syndrome with a G215D mutation of the KCNJ2 gene revealed by diagnostic exome sequencing, is reported.
Chloroethylclonidine interact with Kir2.1 channels in the cytoplasmic pore.
Variability has been found in a three-generation family with Pierre Robin sequence, acampomelic campomelic dysplasia, and intellectual disability due to a novel approximately 1 Mb deletion upstream of SOX9 (show SOX9 ELISA Kits), and including KCNJ2 and KCNJ16 (show KCNJ16 ELISA Kits).
Patients with Dilated Cardiomyopathy and Sustained Monomorphic Ventricular Tachycardia Show Up-Regulation of KCNN3 (show KCNN3 ELISA Kits) and KCNJ2 Genes and CACNG8 (show CACNG8 ELISA Kits)-Linked Left Ventricular Dysfunction
Our results support the concept that endothelial cell Kir2 channels boost vasodilatory signals that are generated by Ca(2 (show CA2 ELISA Kits)+) -dependent activation of IK and SK channels.
Results suggest that a promyogenic cell adhesion molecule (show MCAM ELISA Kits) Cdo (show CDO1 ELISA Kits) signaling is critical for Inward rectifier potassium channel Kir2.1 activities in the induction of myogenic differentiation.
The data suggest that microglial Kir2.1 channels may represent novel therapeutic targets to inhibit excessive reactive oxygen species production by primed microglia in brain pathology.
Three pairs of weak interactions precisely regulate the G-loop gate of Kir2.1 channel.
Suggest that Kir2.1 channels, in part, account for hyperpolarization and associated absence of tone in urinary bladder arterioles.
This finding represents the first functional evidence for a significant role of the dystrophin (show DMD ELISA Kits)-associated protein complex in the regulation of Kir2.x channels.
Intracellular Mg(2 (show MCOLN1 ELISA Kits)+) and SPM (show NPC1 ELISA Kits) therefore may have a synergistic action on the pore-blocking effect, presumably via prohibition of the outward exit of the higher-affinity blocking SPM (show NPC1 ELISA Kits) by the lower-affinity Mg(2 (show MCOLN1 ELISA Kits)+).
Consistent with a role of the K(+) current in amplifying the sensory response, entry of protons through the Zn(2+)-sensitive conductance produces a transient block of the KIR2.1 current.
Mouse neutrophils express functional Kir2.1 channels from bone marrow and liver.
A184R mutation in the inner end of the bundle crossing region of Kir2.1 not only abolishes the inward rectifying features of spermine block but also tends to close the channel pore.
Hypoxic stress up-regulates Kir2.1 expression and facilitates cell proliferation in brain capillary endothelial cells.
Kir2.1 may mediate native Kir (show GEM ELISA Kits) currents responsible for setting resting membrane potential in bovine parotid cells and might be, at least in part, involved in spontaneous secretion in ruminant parotid glands.
There were substantial transmural gradients in Cav1.2 (show CACNA1C ELISA Kits), KChIP2 (show KCNIP2 ELISA Kits), ERG (show KCNH2 ELISA Kits), KvLQT1 (show KCNQ1 ELISA Kits), Kir2.1, NCX1 (show SLC8A1 ELISA Kits), SERCA2a (show ATP2A2 ELISA Kits) and RyR2 (show RYR2 ELISA Kits) at the mRNA and, in some cases, protein level-in every case the mRNA or protein was more abundant in the epicardium than the endocardium.
Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. The encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues. Mutations in this gene have been associated with Andersen syndrome, which is characterized by periodic paralysis, cardiac arrhythmias, and dysmorphic features.
