WitrynaAbout two thirds of the bacterial ribosomal proteins have counterparts in archaeal and eukaryotic ribosomes. Both rRNA and ribosomal proteins are essential for assembly, structure and function of the ribosomes. A few ribosomal proteins are essential for the assembly, but lack a function in the mature ribosome. 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 …
