  1. Numbers include "bridge" sequences qualifying for more than one cluster. Only clusters represented by at least 10 sequences are listed. ASPP, apoptosis stimulating of p53 protein [127]; PP1, protein phosphatase 1 [128]; RUFY, RUN and FYVE domain containing proteins [129]. For species name abbreviations, see Table 1.
