These proteins are the best hits found by probabilistic inference search based on Hidden Markov Models built upon multiple protein alignments of the accessory proteins of the circadian clock of mammals (M. musculus) and insects (D. melanogaster). Those proteins that did not possess the same domains that the query profile are highlighted in red.
