Background: HCN4

HCN4 (hyperpolarization-activated cyclic nucleotide-gated channel 4) is a 120-160 kDa, 1203 amino acid (aa) multipass plasma membrane protein that is a member of the HCN family of potassium channel proteins. It is mainly expressed in cardiac myocytes, thalamus and testis. HCN4 is important for pacemaker function in the heart, and rhythmic activity in the thalamus. Specific mutations can cause Sick Sinus Syndrome 2 (SSS2), a cardiac sinus node malfunction, or Brugada syndrome 8 (BRGDA8), a tachyarrhythmia syndrome. Within aa 1084-1203, human HCN4 shares 92% and 93% aa sequence identity with mouse and rat HCN4, respectively.
