HCN4 | Potassium/Sodium Hyperpolarization-activated Cyclic Nucleotide-Gated Channel 4
Family:
Hyperpolarization-activated cyclic nucleotide-gated channels
Subgroups:
Four different members HCN1-HCN4
Topology:
The channel protein contains six transmembrane domains (S1–S6), four subunits form a functional channel, homotetramers and heterotetramers are possible
Function:
Nonselective gated cation channels, referred to as pacemaker channels, rhythmicity in brain and heart cells
