Common NameToxiferine(F04811)
2D Structure
Description

Toxiferine is a type of curare, a plant toxin known for its use as paralyzing arrow poison by South American indigenous people. It can be extracted from a variety of plants, including Strychnos toxifera and Chondrodendron tomentosum. Curares are active only by an injection. They are harmless if taken orally because curare compounds are too large and too highly charged to pass through the lining of the digestive tract to be absorbed into the blood. (L1256)

General Function:
Receptor binding
Specific Function:
Ionotropic receptor with a probable role in the modulation of auditory stimuli. Agonist binding may induce an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane. The channel is permeable to a range of divalent cations including calcium, the influx of which may activate a potassium current which hyperpolarizes the cell membrane. In the ear, this may lead to a reduction in basilar membrane motion, altering the activity of auditory nerve fibers and reducing the range of dynamic hearing. This may protect against acoustic trauma.
