Numbers indicate number of candidates found. NAs indicate no candidates found. The bait protein sequence which was used to identify the candidates is indicated as the column header. ‘Arthropod’ and ‘Mammalian’ refer to the type of circadian clock the bait protein sequence originates from (Drosophila melanogaster and Mus musculus respectively). Circadian clock protein abbreviations as in Table 2. Phylum abbreviations: Ar - Arthropoda, An - Annelida, Ph - Phoronida, Ch - Chordata, Ec - Echonodermata, Cn - Cnidaria
