This toxin shows both immunosuppressive and anti-inflammatory activities (PubMed:28077339). It has the potential to inhibit human T cell activation, since it reduces IL-2 secretion and the expression of T cell activation marker CD69 and acts as a anti-inflammatory agent, since it provokes the reduction of secretion of both IFN-gamma and TNF-alpha (PubMed:28077339). In vivo, the delayed-type hypersensitivity response in rat autoimmune disease model is ameliorated in the presence of this toxin (PubMed:28077339). Acts by blocking Kv1.3/KCNA3 potassium channels of T-lymphocytes (By similarity). Expressed by the venom gland. Has the structural arrangement of an alpha-helix connected to antiparallel beta-sheets by disulfide bonds (CS-alpha/beta). Recombinant toxin does not cause hemolysis in human erythrocytes. Belongs to the short scorpion toxin superfamily. Potassium channel inhibitor family. Alpha-KTx 23 subfamily.
