Dicer cleaves 5'-extended microRNA precursors originating from RNA polymerase II transcription start sites.

abstract：:Post-translational modifications (such as ubiquitination) of clock proteins are critical in maintaining the precision and robustness of the evolutionarily conserved circadian clock. Ubiquitination of the core clock transcription factor BMAL1 (brain and muscle Arnt-like 1) has recently been reported. However, it remain...
