Reliable, high throughput KV7 assays are important because KV7 ion channels play a key role in regulating neuronal excitability, which is closely linked to both pain signalling and seizure activity.
Kv7 channels are a family of voltage gated potassium ion channels that play a key role in controlling cellular excitability. These channels open in response to changes in membrane voltage and allow potassium ions to leave the cell, helping to stabilise the membrane potential and regulate electrical signalling.
In neurons, Kv7 channels contribute to the M current, a slowly activating and non inactivating potassium current that limits repetitive firing and helps prevent excessive neuronal activity. The KV7 family includes several subtypes, known as KV7.1 to KV7.5, which are encoded by the KCNQ genes. KV7.2 and KV7.3 are particularly important in the central nervous system, where they are widely expressed in excitatory neurons.
In ion channel research, KV7 channels are of significant interest because altered channel function has been linked to a range of neurological disorders, including epilepsy, developmental encephalopathies, neuropathic pain and hearing disorders. KV7 channels are also important pharmacological targets, with compounds that modulate channel activity being investigated for therapeutic applications.
Reliable, high throughput KV7 assays are important because KV7 ion channels play a key role in regulating neuronal excitability, which is closely linked to both pain signalling and seizure activity.
Kv7 ion channels are highly relevant to epilepsy because they are voltage gated potassium ion channels that help regulate neuronal excitability and suppress excessive electrical firing in the brain.
