HsTX1, a 34-residue, C-terminally amidated peptide isolated from the scorpion Heterometrus spinnifer, features four disulfide bridges and acts as a potassium channel inhibitor. It exhibits an IC50 of 12 pM for Kv1.3, impeding T EM cell activation and diminishing inflammation in autoimmune conditions [1] [2] [3].
