DGCR8 is a component of the canonical microprocessor complex for microRNA biogenesis. Here the authors implicate DGCR8 in heterochromatin maintenance and aging attenuation independent of its miRNA-processing activity through Lamin B1, KAP1 and HP1 interaction. DGCR8 overexpression can alleviate aging and senescence
