Match the following

Column I	Column II	Column III
A. Cytochalasin D	i. A sponge toxin	a. Enhances nucleation by binding and stabilizing actin dimers and thereby lowering the critical concentration.
B. Latrunculin	ii. A fungal alkaloid	b. Binds and sequesters G-actin, inhibiting it from adding to a filament end.
C. Jasplakinolide	iii. The “angel of death” mushroom	c. Binds at the interface between subunits in F-actin, locking adjacent subunits together and preventing actin filaments from depolymerizing.
D. Phalloidin		d. Depolymerizes actin filaments by binding to the (+) end of F-actin, where it blocksfurther addition of subunits.
