Metacaspases are related to caspases and paracaspase. The metacaspases are Arginine/Lysine-specific, in contrast to caspases, which are Aspartate-specific. Metacaspases are found in plants, fungi, and "protists," but not in slime mold or animals, with one recent exception where both type I and type II metacaspases were found in the genome of Monosiga brevicollis, possibly as a result of an unusual horizontal gene transfer between two eukaryotes. In an analogous manner to caspases, metacaspases induce programmed cell death in both plants and fungi (yeast).
