description | Protein which interferes with the function of chloride channels which are membrane proteins forming a channel in a biological membrane selectively permeable to chloride ions. Chloride channels include voltage-gated chloride channels (ClC), ionotropic GABA receptors (ligand-gated ion channels activated by GABA) and CFTR ion channels (ABC transporter-class ion channels). Toxins that target these channels are found in venom of several species including scorpions and snakes |
