Gene Name
| HCN2 |
Protein Type
| Transporter |
Biological Properties |
General Function
| Involved in ion channel activity |
Specific Function
| Hyperpolarization-activated ion channel exhibiting weak selectivity for potassium over sodium ions. Contributes to the native pacemaker currents in heart (If) and in neurons (Ih). Produces a large instantaneous current. Activated by cAMP. Modulated by intracellular chloride ions and pH; acidic pH shifts the activation to more negative voltages |
