HCN Channel

Hyperpolarization activated cyclic nucleotide gated channels

Hyperpolarization- and Cyclic Nucleotide-gated (HCN) channels are a family of six transmembrane domain, single pore-loop, hyperpolarization activated, non-selective cation channels. The HCN family consists of four members (HCN1-4). HCN channels represent the molecular correlates of I(h), a hyperpolarization-activated current best known for its role in controlling heart rate and in the regulation of neuronal resting membrane potential and excitability.

HCN channels are unique among vertebrate voltage-gated ion channels, in that they have a reverse voltage-dependence that leads to activation upon hyperpolarization. HCN channels are encoded by four genes (HCN1-4) and are widely expressed throughout the heart and the central nervous system.

    Sp-8-Br-cGMPS
    Agonist
    Sp-8-Br-cGMPS is an analog of cGMP. Sp-8-Br-cGMPS is an agonist for cGMP-gated cation channels (CNG channels), with an EC50 of 106.5 μM. Sp-8-Br-cGMPS induces the currents, without the ability to stabilize the channel open state as a full agonist.

    Rp-8-Br-cGMPS
    Activator
    Rp-8-Br-cGMPS (Rp-8-bromo-Cyclic GMPS) sodium salt is a potent Ca2+-ATPase activator. Rp-8-Br-cGMPS is also an agonist of the rod CNG channel and an inhibitor of PKG. Rp-8-Br-cGMPS sodium salt mediates cytosolic Ca2+ reduction by activating Ca2+-ATPase and subsequently removing Ca2+ from the cell.
