*From [32]. †From [19]. ‡Note that this number of families is lower than that previously published [21]. This is probably because the published number was calculated from the alignment of the middle part of the sequences, which is more diverse, particularly for transmembrane domains TMIII and TMIV. Nd, not determined. |
