A philogenetic tree comparing the sequence of recoverin with those of other coat proteins from different species was constructed using the Darwin program. GenBank accession codes are: Bos taurus recoverin P21457[GenBank], Mus musculus recoverin P34057 [GenBank] , Homo sapiens Recoverin P35243 [GenBank], Rana catesbeiana S-modulin P31227 [GenBank], Gallus gallus visinin P22728 [GenBank], Drosophila melanogaster neurocalcin P42325 [GenBank], Gallus gallus vilip3 P42324 [GenBank], Mus musculus vilip3 P35333 [GenBank], Homo sapiens vilip3 P37235 [GenBank], Homo sapiens hippocalcin P41211 [GenBank], Mus musculus hippocalcin P32076 [GenBank], Bos taurusneurocalcin d P29554 [GenBank], Homo sapiens vilip1 P 28667 [GenBank], Rattus norvegicus vilip2 P35332 [GenBank], Xenopus laevis ncs-1 Q91614 [GenBank], Homo sapiens ncs-1 P36610 [GenBank], Schizosaccharomyces pombe ncs-1 Q099711 [GenBank], Caenorhabditis elegans ncs-1 P36608 [GenBank], Saccharomyces cerevisiae ncs-1 Q06389 [GenBank], Drosophila melanogaster frequenin P37236 [GenBank], Aplysia californica aplycalcin Q16982 [GenBank], Caenorhabditis elegans ncs2 P36609 [GenBank], Rana pipiens GCIP O73763 [GenBank], Rana pipiens GCAP2 O73762 [GenBank], Gallus gallus GCAP2 P79881 [GenBank], Gallus gallus GCAP1 P79880 [GenBank], Rana pipiens GCAP1 O73761 [GenBank], Homo sapiens GCAP1 P43080 [GenBank], Bos taurus GCAP1 P46065 [GenBank], Mus musculus GCAP1 P43081 [GenBank], Homo sapiens GCAP2 Q9UMX6 [GenBank], Bos taurus GCAP2 P51177 [GenBank], Homo sapiens GCAP3 O95843 [GenBank], Homo sapiens calsenilin Q9Y2W7 [GenBank], Mus musculus calsenilin Q9QXT8 [GenBank], Rattus norvegicus calseninlin Q9JM47 [GenBank], Homo sapiens calmodulin, hs- Homo sapiens, bt- Bos taurus, m- Mus musculus, rp- Rana catesbeiana, gg- Gallus gallus, dm- Drosophila melanogaster, G -Gallus , rn -Rattus norvegicus, xe- Xenopus laevis, ce- Caenorhabditis elegans, ac- Aplysia californica, sc- Saccharomyces cerevisiae, rp- Rana pipiens.
