The use of bacteriophage T7 is presented as a peptide display platform to identify short binding sequences for PDZ domain proteins. Two different domains are examined, the 10th PDZ domain (PDZ10) of the multi-PDZ domain protein 1 (MUPP1) and the third PDZ domain (PDZ3) of postsynaptic density-95 (PSD-95) protein. Using the T7Select 415-1b construct, which(More)
It remains controversial whether the highly homologous ribosomal protein (RP) paralogs found in lower eukaryotes have distinct functions and this has not been explored in vertebrates. Here we demonstrate that despite ubiquitous expression, the RP paralogs, Rpl22 and Rpl22-like1 (Rpl22l1) play essential, distinct, and antagonistic roles in hematopoietic(More)
Most yeast ribosomal protein genes are duplicated and their characterization has led to hypotheses regarding the existence of specialized ribosomes with different subunit composition or specifically-tailored functions. In yeast, ribosomal protein genes are generally duplicated and evidence has emerged that paralogs might have specific roles. Unlike yeast,(More)
For almost five decades, antibiotics have been used successfully to control infectious diseases caused by bacterial pathogens. More recently, however, two-thirds of bacterial pathogens exhibit resistance and are continually evolving new resistance mechanisms against almost every clinically used antibiotic. Novel efforts are required for the development of(More)
Ribosomal RNA is the catalytic portion of ribosomes, and undergoes a variety of conformational changes during translation. Structural changes in ribosomal RNA can be facilitated by the presence of modified nucleotides. Helix 31 of bacterial 16S ribosomal RNA harbors two modified nucleotides, m²G966 and m⁵C967, that are highly conserved among bacteria,(More)
Ribosomal proteins have long been known to serve critical roles in facilitating the biogenesis of the ribosome and its ability to synthesize proteins. However, evidence is emerging that suggests ribosomal proteins are also capable of performing tissue-restricted, regulatory functions that impact normal development and pathological conditions, including(More)
