Fig. 7 Phylogenetic tree and schematic structures of Caenorhabditis elegans calpains.

(A) Phylogenetic tree of C. elegans 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)
GR: glycine-rich domain
MIT: microtubule interacting and transport motif
Zn: Zn-finger motif
SOH: SOL-homology domain
CI and CII: conserved regions I and II with unknown function, respectively.
