22396414 Increased excitability and decreased dendritic arborization are associated with downregulation of inward rectifier potassium channels (Kir2.1/2.3).
20424473 Observational study of gene-disease association. (HuGE Navigator)
19635485 TIP-1 may act as an important regulator for the endocytic pathway of Kir2.3.
18503768 The data suggest that Kir2.3 plays a potentially important role in I(K1) currents in neonatal rat cardiomyocytes.
18453743 possibility of intramolecular interactions of the residue Kir2.3(H117) with conserved cysteines in close proximity to the selectivity filter
18180291 Kir2.3 is internalized by an AP-2 clathrin-dependent mechanism.
16373386 In conclusion, the data are consistent with the universal mechanism of rectification in Kir2 channels, but also point to significant, and physiologically important, quantitative differences between Kir2 isoforms.
16258766 Results describe the regulation of inwardly rectifying potassium current and its main molecular correlates, Kir2.1, Kir2.2 and Kir2.3 channels, by endothelin-1 in human atrial cardiomyocytes.
15958527 Kir2.2 and Kir2.1 are primary determinants of endogenous K(+) conductance in HAECs under resting conditions and that Kir2.2 provides the dominant conductance in these cells.
