Annotations are based on BLASTp results of the Swissprot database as well as phylogenetic analyses of cryptochromes17 and basic helix-loop-helix genes i.e., Hes/Hey-like;26. Columns labeled “peak” indicate times of maximum expression. In many cases, multiple microarray probes corresponded to a single SeqIndex. The fraction of probes showing the described circadian pattern is indicated parenthetically.
