生化/生理作用
A 58-residue protein whose binding to various serine proteases has been extensively studied. It is highly homologous to a family of mamba snake dendrotoxin proteins that inhibit various K+ channels. It also binds to an intracellular site associated with the large conductance Ca2+-activated K+ channel..
