Paracaspase

Paracaspases (human: MALT1) are related to caspases present in animals and slime mold, in contrast to metacaspases which are present in plants, fungi and "protists".

Paracaspases are more similar to caspases than metacaspases are, indicating that this group of (putative) proteases diverged from caspases from a common metacaspase ancestor. The phylogenetic distribution is a bit confusing, since slime mold diverged earlier than the animal/fungal split.
