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.

    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.

    VUANT1
    Antagonist
    VUANT1 (VU0183254) is an allosteric antagonist of insect odorant receptor ion channels, which has the activity of inhibiting insect odorant receptor signaling. VUANT1 can inhibit the activation of insect odorant receptors through allosteric regulation, which is important for the study of the molecular mechanism of insect olfactory signaling. Although it may be of limited use in insect control programs, it can be used as a pharmacological tool to study related mechanisms.
