Enzyme Function | FUNCTION: Toxin with unknown function in healthy organisms. On glioma cells, inhibits chloride currents in a voltage-dependent manner (when tested on gliomas cells) (PubMed:17166663). Also interacts with MMP2 and significantly inhibits its catalytic activity (PubMed:21424168). May be internalized with chloride channels (probably ClC-3/CLCN3) and MMP2, thus inhibiting the chloride channels necessary for cell shrinkage and tumor propagation. {ECO:0000269|PubMed:17166663, ECO:0000269|PubMed:21424168}. |
