The nucleolus is the ribosome biogenesis center. The nucleolar structure is disrupted upon entry into mitosis and is formed in early G1 phase. To understand the molecular mechanisms of nucleolar assembly and disassembly, we have studied the mechanism of association between factors involved in pre-ribosome RNA (rRNA) processing and rRNA gene chromatin ...

Gene heterogeneity: a basis for alternative 5.8S rRNA processing
Biochemistry, 1984Two bands of 5.8S rRNA were observed when the total RNA isolated from rat or mouse tissue was separated by electrophoresis on high-resolution polyacrylamide gels under denaturing conditions. The minor form, with a lower mobility, represented 15-35% of the total 5.8S rRNA, depending on the source of the tissue.

Expression of mouse and frog rRNA genes: transcription and processing
Molecular and Cellular Biochemistry, 1991This article summarizes a number of lines of investigation of rRNA gene expression that are ongoing in the laboratory. These studies focus on mouse and frog, two distant vertebrate species. One major conclusion is that the basic properties of rRNA gene expression appear remarkably well conserved in evolution, with only relatively minor perturbations ...

Characterization of a crucifer plant pre-rRNA processing complex
Biochemical Society Transactions, 2004In cruciferous plants, the primary pre-rRNA cleavage site (P site) is immediately downstream of four similar, highly conserved sequences (A1, A2, A3 and B) located within the 5′-ETS (5′-external transcribed spacer). In the present study, we describe the characterization of a plant NF D (nuclear factor D) that binds and interacts specifically with this ...

Biochemistry, 2005
Despite the large differences in their length and nucleotide composition, comparative analyses of the internal transcribed spacer 1 (ITS1) of widely divergent eukaryotes have suggested a simple core structure consisting of a central extended hairpin and lesser hairpin structures at the maturing junctions [Lalev, A. I., and Nazar, R. N. (1998) J.

Ribonuclease E Is Involved in the Processing of 5-S rRNA from a Number of rRNA Transcription Units
European Journal of Biochemistry, 1982Strains of Escherichia coli having a thermosensitive RNase E produce a number of 5-S ribosomal RNA precursors at a non-permissive temperature. One of these precursors, 9-S RNA, was reported earlier [Ghora, B.K. and Apirion, D. (1978) Cell, 15, 1055-1066]. Here we show the existence of additional precursors to 5-S rRNA, originating from a number of rRNA

Quantitative Northern Blot Analysis of Mammalian rRNA Processing
2016Assembly of eukaryotic ribosomes is an elaborate biosynthetic process that begins in the nucleolus and requires hundreds of cellular factors. Analysis of rRNA processing has been instrumental for studying the mechanisms of ribosome biogenesis and effects of stress conditions on the molecular milieu of the nucleolus.

Making Ribosomes: Pre-rRNA Transcription and Processing
2014Ribosomes are essential, intricate cellular machines that translate mRNA into protein in all cells. The process of building a ribosome is highly complex. The ribosomal RNA (rRNA) has to be properly synthesized, processed, and assembled with ribosomal proteins in the cell nucleolus.
