Validated All-in-One™ qPCR Primer for KCNJ4(NM_004981.1) Search again
Powered by BiozBy default, qPCR primer pairs are designed to measure the expression level of the splice variant (accession number) you selected for this gene WITHOUT consideration of other possible variants of this gene. If this gene has multiple variants, and you would like to measure the expression levels of one particular variant, multiple variants, or all variants, please contact us for a custom service project at inquiry@genecopoeia.com.

Each All-in-One™ qPCR Primer is experimentally validated to yield a single dissociation curve peak and to generate a single amplification of the correct size for the targeted gene. A cDNA Pool, containing reverse transcript products of 8 different human tissue total RNA(Liver, Testis,Muscle,Thyroid,Brain,Spleen,Stomach,Small Intestine)),was used as the qPCR validation template. qPCR was performed using 0.2 µM primer with 2XAll-in-One™ qPCR Mix (Catalog#: QP001,QP002,QP004,QP005). Reactions were incubated for 10min. at 95°C, followed by 40 cycles of 95°C for 10 sec.; 60°C, 20 sec. and 72°C, 15sec. using Bio-Rad iQ5™ Instrument. At the end of the last cycle, temperature was increased from 72 to 95°C to produce a melting curve. Panel A: Validated Result for Amplification Curve; Panel B: Validated Result for Melting Curve. |

Summary
Several different potassium channels are known to be involved with electrical signaling in the nervous system. One class is activated by depolarization whereas a second class is not. The latter are referred to as inwardly rectifying K+ channels, and they have a greater tendency to allow potassium to flow into the cell rather than out of it. This asymmetry in potassium ion conductance plays a key role in the excitability of muscle cells and neurons.
Gene References into function
- 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.
- 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.
- 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.
- Kir2.3 is internalized by an AP-2 clathrin-dependent mechanism.
- possibility of intramolecular interactions of the residue Kir2.3(H117) with conserved cysteines in close proximity to the selectivity filter
- The data suggest that Kir2.3 plays a potentially important role in I(K1) currents in neonatal rat cardiomyocytes.
