L7Ae, a member of the L30 family of ribosomal proteins, is a multifunctional protein that is a component of the archaeal ribosome, the C/D RNPs and the H/ACA RNPs (9,11). The C/D motifs that have been characterized to date form an RNA structure known as a Kink-turn (K-turn) (9,22). The K-turn, found in all three domains of life, was ...

WebbThe adaptation of mRNA stability to environmental changes is a means of cells to adjust the level of gene expression. The Escherichia coli ompA mRNA has served as one of the paradigms for regulated mRNA decay in prokaryotes. The stability of the WebbRibosome profiling is a recently developed high-throughput sequencing technique that captures approximately 30 bp long ribosome-protected mRNA fragments during translation. Because of alternative splicing and repetitive sequences, a ribosome-protected read may map to many places in the transcriptome, leading to discarded or arbitrary …
WebbThe scanning model posits that, upon cap-dependent attachment to mRNA, ribosomal small subunits (SSUs) move in a 5′ to 3′ direction (at the expense of energy; ‘powered’ motion), while the 5′UTR nucleotide sequence is being probed for codon:anticodon and local ‘nucleotide context’ interactions [ 1, 2, 3, 4, 5, 6 ].
