OsK1 is a 38-residue peptide with 3 disulphide bridges and is found in the venom of the scorpion. It is potently active on voltage-gated Kchannels Kv1.1, Kv1.2 and Kv1.3, and moderately active on the type 1 intermediate-conductance Cat-activated channel K3.1. Derivatives of OsK1, particularly involving truncation or point mutations, have been developed to enhance the activity against and selectivity for the Kv1.3 channel. This renders the derivatives likely candidates for the treatment of autoimmune diseases, including multiple sclerosis. Such use may be alone or in combination therapy with maurotoxin, another scorpion toxin.
