corrigendum: Extensive and divergent circadian gene expression in liver and heart

Nature 417, 78–83 (2002). Two errors of gene annotation have come to our attention. Although we refer to Zfp36 in the text, the gene identified in our data sets was Zfp36l-1 (Zfp36-like 1; NCBI RefSeq accession number NM_007564). Current evidence suggests that Zfp36l-1 protein and its close relatives are RNA-binding factors rather than transcription factors1,2,3.
