Fig. 8 Phylogenetic tree and schematic structures of Schistosoma mansoni calpains.

(A) Phylogenetic tree of S. mansoni and human calpains. The tree was drawn using the neighbor-joining/bootstrap method after aligning all the sequences using MAFFT v6.240 (strategy: E-INS-i). (B) Schematic structures.

Abbreviations used for domain names:
CysPc: calpain-like cysteine protease sequence motif defined in the conserved domain database at the National Center for Biotechnology Information (cd00044), which is composed of two protease core domains 1 and 2 (PC1 and PC2).
PC1: protease core domain 1
PC2: protease core domain 2
CBSW: calpain-type beta-sandwich domain (formerly called "C2-domain-like (C2L)" domain)
PEF: penta-EF-hand domain
P-rich: Pro-rich region
DIS: Drosophila-type insertion sequence
MIT: microtubule interacting and transport motif
USP: ubiquitin-specific peptidase
