Ribosomes are compositionally heterogeneous between species and even within the same cell, as evidenced by the existence of cytoplasmic and mitochondria ribosomes within the same eukaryotic cells. Certain researchers have suggested that heterogeneity in the composition of ribosomal proteins in mammals is important for gene regulation, i.e., the specialized ribosome hypothesis. However, this hypothesis is controversial and the topic of ongoing research. WitrynaPNO1 (Dim2 or Rrp2 or YOR145), a highly conserved regulator of ribosome assembly from yeast to mammals, is involved in forming the 90S pre-ribosome and plays an essential role in the late stage of 40S small subunit maturation. Recent studies have found that PNO1 is involved in the progression of a variety of tumors and is highly …
