Dinoflagellate transcriptomes contain cold shock domain proteins as the major component of the proteins annotated as transcription factors. We show here that the major family of cold shock domain proteins in the dinoflagellate Lingulodinium do not bind specific sequences, suggesting that transcriptional control is not a predominant mechanism for regulating gene expression in this group of protists.
