Pore-forming toxin with nematicidal activity (PubMed:26795495, PubMed:27576487). In infected C.elegans, induces an increase in intracellular Ca(2+) resulting in necrosis of host intestinal cells (PubMed:26795495). Also, induces the expression of aspartic protease asp-1 (PubMed:26795495). Interacts with C.elegans aspartic protease asp-1; the interaction prevents Cry6Aa proteolysis by host gut proteases. Probably secreted as a soluble protein that then inserts into the host membrane and forms pores. The crystal protein is produced during sporulation and is accumulated both as an inclusion and as part of the spore coat. Belongs to the cry6A endotoxin family.
