This peptide does not have cytotoxic activities. Homodimer; disulfide-linked. Expressed by the venom gland and reservoir. Belongs to the formicidae venom precursor-01 superfamily. Ant pilosulin family. M.banksi is a member of the M.pilosula complex, but is clearly distinct from M.pilosula species. It is why the nomenclature proposed by Touchard et al., 2016 is slightly modified in this entry.
