Conotoxin | 129129-65-3

Conotoxins yog ib pab pawg sib txawv ntawm me me peptide toxins uas tsim los ntawm lub khob hliav qab (genus Conus). Cov snails marine no muaj nyob rau hauv hiav txwv tropical thiab subtropical thiab paub txog lawv txoj kev yos hav zoov tshwj xeeb. Cone snails siv venom los immobilize lawv prey, uas feem ntau muaj lwm yam marine kab mob xws li ntses thiab worms.

Conotoxins muaj nyob rau hauv cov venom ntawm cone snails thiab pab ntau lub hom phiaj, xws li subduing prey thiab tiv thaiv tawm tsam predators. Cov peptides hauv conotoxins muaj ntau yam kev ua haujlwm tshuaj thiab tuaj yeem cuam tshuam nrog cov receptors tshwj xeeb thiab cov ion channel hauv lub paj hlwb. Vim lawv qhov tshwj xeeb tshwj xeeb rau qee lub hom phiaj, conotoxins tau nyiam los ntawm cov kws tshawb fawb rau lawv cov peev xwm siv tshuaj thiab kev tsim tshuaj.

Conotoxins tau muab faib ua ntau tsev neeg raws li lawv cov qauv thiab lub hom phiaj receptors lawv cuam tshuam nrog. Qee tsev neeg muaj xws li:

A-conotoxins: Target nicotinic acetylcholine receptors.

M-conotoxins: Thaiv voltage-gated sodium channels.

O-conotoxins: Sib cuam tshuam nrog voltage-gated calcium channels.

T-conotoxins: Lub hom phiaj voltage-gated potassium channels.

Cov co toxins no tau pom cov lus cog tseg hauv kev txhim kho cov tshuaj tshiab rau kev tswj xyuas qhov mob, mob hlwb, thiab lwm yam mob. Cov kws tshawb fawb tshwj xeeb yog xav txog lawv lub peev xwm los xaiv cov kev hloov kho tshwj xeeb, ua rau lawv muaj txiaj ntsig zoo hauv kev tsim cov tshuaj ntau dua thiab siv tau zoo.
