Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

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). May mediate responses to sour stimuli.1 Publication

Activated by cAMP, and at 10-100 times higher concentrations, also by cGMP. cAMP binding promotes tetramerization and formation of an active channel. Compared to other family members, cAMP has less stimulatory effect on HCN1 because part of the molecules already contain bound cAMP and form homotetramers when cAMP levels are low (By similarity).By similarity
