Toxin with unknown function in healthy organisms. Suppress growth and migration of glioma cells and decreases the mRNA expression of annexin A2 (ANXA2) and forkhead box protein M1 (FOXM1), two key molecules in the progression and invasion of glioma (PubMed:35524923). May affect chloride channel (By similarity). May interact with MMP2 and inhibit its catalytic activity (By similarity) (Ref.2). In vivo, is not toxic when administrated to mice at high doses (PubMed:35524923). Expressed by the venom gland. The presence of a 'disulfide through disulfide knot' structurally defines this protein as a knottin. Belongs to the short scorpion toxin superfamily. Chloride channel inhibitor family.
