Key features of each of the six NLR-C subgroups as identified from zebrafish (Danio rerio) and round goby. Each of the groups is characterized by the presence of a highly conserved Walker A Motif and either the presence or absence of specific C- and N-terminal domains (PYD and B30.2). x denotes a variable amino acid, + and − denote whether the denoted domains are characteristically present/absent in the group
