- aTotal number of species in which a phosphosite was present, including the query organism. We did not identify any sites with homologs in all six datasets. bThe number of expected sites assuming independent chances of conservation (the chance of a specific site being conserved in one species is independent of the presence or absence of that same site in other species).
