The E2F family of transcription factors are critical regulators of the cell cycle and have also been implicated in apoptosis, development, DNA damage checkpoints, and differentiation. Retinoblastoma (Rb) proteins interact with E2F to regulate transcription, and several mechanisms have been proposed for Rb-E2F transcriptional regulation. We designed(More)
Germline von Hippel-Lindau tumour suppressor gene (VHL) mutations cause renal cell carcinomas, haemangioblastomas and phaeochromocytomas in humans. Mutations in VHL also occur in sporadic renal cell carcinomas. The protein encoded by VHL, VHL, is part of the ubiquitin ligase that downregulates the heterodimeric transcription factor Hif under well-oxygenated(More)
Vascular endothelial dysfunction is now recognized as a common phenomenon in an array of cardiovascular disorders. Production of nitric oxide via the endothelial isoform of nitric oxide synthase [eNOS (previously termed NOS3 or ecNOS)] is vital for a healthy endothelium; several polymorphic variations of the gene encoding eNOS (NOS3) are now known and have(More)
Ferritin is a ubiquitous and highly conserved protein which plays a major role in iron homeostasis. We have identified and sequenced a full-length cDNA for murine ferritin heavy chain. The isolated cDNA is 819 nucleotides in length. It includes 546 nucleotides which encode a protein of 182 amino acids, a 5' noncoding sequence of 120 nucleotides, and a(More)
Pax3 is an essential myogenic regulator of fetal and embryonic development, but its role in postnatal myogenesis remains a topic of debate. We show that constitutive expression of Pax3 in postnatal, juvenile mouse skeletal muscle stem cells, a subset of the heterogeneous satellite cell pool highly enriched for myogenic activity, potently induces(More)
Genetic research on influenza virus biology has been informed in large part by nucleotide variants present in seasonal or pandemic samples, or individual mutants generated in the laboratory, leaving a substantial part of the genome uncharacterized. Here, we have developed a single-nucleotide resolution genetic approach to interrogate the fitness effect of(More)
We report the cloning and sequencing of cDNA encoding a chicken filamin protein. The 2,567 amino acid protein contains an NH2-terminal 267 amino acid actin-binding domain followed by a series of 24 repeating units that are each approximately 95 amino acids in length. The overall primary structure of filamin closely resembles that of human actin-binding(More)
UNLABELLED Viral proteins often display several functions which require multiple assays to dissect their genetic basis. Here, we describe a systematic approach to screen for loss-of-function mutations that confer a fitness disadvantage under a specified growth condition. Our methodology was achieved by genetically monitoring a mutant library under two(More)
17 A novel genome-wide genetics platform is presented in this study, which permits functional 18 interrogation of all point mutations across a viral genome in parallel. Here we generated the first 19 fitness profile of individual point mutations across the influenza virus genome. Critical residues 20 on the viral genome were systematically identified, which(More)
