procesin
Procesin is a protein found in the venom of the Brazilian wandering spider (Phoneutria nigriventer). It is a potent neurotoxin that acts on the central nervous system, causing a variety of symptoms including muscle spasms, pain, and in severe cases, respiratory failure. Procesin is used in scientific research to study the mechanisms of pain and to develop new pain management therapies. It is also used in the production of some snake antivenoms, as it can neutralize the effects of certain snake venoms. Procesin is a small, basic protein with a molecular weight of approximately 3.5 kDa. It is composed of 31 amino acids and has a unique three-dimensional structure that allows it to bind to specific receptors in the nervous system. Procesin is highly toxic, with an LD50 (lethal dose for 50% of the population) of approximately 0.1 mg/kg in mice. It is important to note that procesin should only be handled by trained professionals in a controlled environment, as it can cause severe harm or death if mishandled.
