Abstract:
Translation is a key process during gene expression: to produce proteins, ribosomes translate the coding sequences of mRNAs. However, vertebrate genomes contain more translation potential than these annotated coding sequences: translation has been detected in many non-coding RNAs and in the non-coding regions of mRNAs. To understand the role of such translation in vertebrates, I investigated: 1) the distribution of translation in vertebrate long non-coding RNAs, and 2) the effects of translation in the 5’ leaders of vertebrate mRNAs.

Abstract:
The recruitment of ribosomes to the 5' end of mRNAs in eukaryotic cells is generally thought to be the rate-limiting step of translation initiation and this process is mediated by the eukaryotic initiation factor 4F complex (eIF4F). This complex consists of three subunits: eIF4E, a mRNA-cap binding protein, eIF4A, a RNA helicase and eIF4G, a large molecular scaffold that mediates the binding of mRNA to ribosomes. Deregulation of translation initiation through eIF4F activation has been widely observed in human cancers. The eIF4F complex lies downstream of key signalling pathways involved in onc

Abstract:
<p> Herpes Simplex Virus Type 1 is a member of the <i>alphaherpesvirinae </i> subfamily within the family <i>Herpesviridae</i>. This virus has both a lytic and latent cycle. Primary infection occurs when the virus enters epithelial cells around the mucosal lining of the nose and mouth. Within the epithelial cells, the virus undergoes an active lytic infection, causing an ulcerated blister, more famously known as a 'cold sore' or 'fever blister'. Once HSV enters the nearby sensory neurons the genome is transported to the neuronal cell body where its latency associated transcripts are activated

Abstract:
In eukaryotes, the initiation phase of protein synthesis or translation is a multi-step process that culminates in the positioning of the SOS ribosome at the initiation codon of a messenger RNA (mRNA). Recognition of the cap structure by eukaryotic initiation factor 4F (etF4F; composed of three subunits: the cap-binding protein e1F4E, the RNA-helicase eIF4A and the scaffolding protein eIF4G) facilitates this process. The ability of eIF4F to bind to the cap, as a result of the Cap:eIF4E interaction is of particular importance, as it is the major target of translational regulatory mechanism.<br>

Abstract:
In eukaryotes, control of protein synthesis or translation is critical for maintenance of cellular function and adaptation to environmental stimuli or stresses. The entire process of producing a functional protein molecule from an mRNA template is elaborately controlled and involves several integrated phases. It is the initiation phase of recruiting the protein synthesis machinery to an mRNA that is rate-limiting for translation. Importantly, a major regulatory mechanism of translation initiation is performed by the eIF4E-binding proteins (4E-BPs). These small proteins interact with the mRNA 5

Abstract:
The poly(A) binding protein (PABP) is an essential translation factor that enhances protein synthesis and protects mRNAs from degradation. PABP is composed of four RNA recognition motifs (RRM) at its N-terminal and a peptide-interacting C-terminal domain. PABP-interacting proteins 1 (Paip1) and 2 (Paip2) were found to respectively stimulate or inhibit translation. Both Paip 1 and 2 contain two PABP interacting regions (PAM1 and PAM2). In this study, NMR was used to elucidate the mechanism by which Paip2 down-regulates translation through disruption of PABP's binding to poly(A) RNA. A fragment

Abstract:
Mitochondria are the organelles where respiration occurs. The yeast mitochondrial genome encodes only 8 proteins, therefore the organelle depends on the nuclear genome for many proteins required in different steps of mitochondrial gene expression. Regulation of mRNA stability, processing and translation are important steps in gene expression within the mitochondrion. Cbp1, a protein encoded by the nuclear gene CBP1, is required specifically for stabilization of precursor and mature cytochrome b (COB) RNA, which is encoded in the mitochondrial genome. Previous work identified a cis-element, CCG

Abstract:
Two forms of glutamine synthetase (GS) have been isolated from three-day old etiolated soybean hypocotyls by ammonium sulfate precipitation and DEAE-cellulose chromatography. The GS isoforms were eluted from a 30 ml DEAE-cellulose column using 0.14 M KC1 and 0.175 M KC1 and from a 1.0 ml DEAE-cellulose column using 0.08 M KC1 and 0.14 M KC1. The two isoforms of soybean GS have a molecular weight of about 392,000 daltons as indicated by in gel enzyme assays and staining of protein bands. The poly(A)+RNA specific for GS synthesis was isolated using phenol and chloroform followed by Hybond mAP pa

Here we show that stimulation of macrophages through Toll-like receptors (TLR) disrupts the assembly of mitochondrial electron transfer chain (ETC) complexes

Abstract:
Innate immune signaling pathways initiate host defenses against viral pathogens. Receptors specific for viral nucleic acids activate these pathways culminating in cell-to-cell communication and/or cell death. In mammals, this cell- to-cell communication is achieved through the production of interferons and pro- inflammatory cytokines, which activate antiviral defenses in uninfected neighboring cells and instruct adaptive immune responses. The production of these signaling molecules is essential for the defense against viral infection, but must also be tightly regulated to prevent unnecessary i
