The Adam family metalloprotease Kuzbanian regulates the cleavage of the roundabout receptor to control axon repulsion at the midline.
(2010)Slits and their Roundabout (Robo) receptors mediate repulsive axon guidance at the Drosophila ventral midline and in the vertebrate spinal cord. Slit is cleaved to produce fragments with distinct signaling properties. In ... -
CARDINAL, a novel caspase recruitment domain protein, is an inhibitor of multiple NF-kappa B activation pathways.
(2001)Proteins possessing the caspase recruitment domain (CARD) motif have been implicated in pathways leading to activation of caspases or NF-kappaB in the context of apoptosis or inflammation, respectively. Here we report the ... -
Caspase-1 promiscuity is counterbalanced by rapid inactivation of the processed enzyme.
(2011)Members of the caspase family of cysteine proteases coordinate the highly disparate processes of apoptosis and inflammation. However, while hundreds of substrates for the apoptosis effector caspases (caspase-3 and caspase-7) ... -
A common theme in interaction of bacterial immunoglobulin-binding proteins with immunoglobulins illustrated in the equine system
(The American Society for Biochemistry and Molecular Biology, 2008)The M protein of Streptococcus equi subsp. equi known as fibrinogen-binding protein (FgBP) is a cell wall-associated protein with antiphagocytic activity that binds IgG. Recombinant versions of the seven equine IgG subclasses ... -
Comparing Pathways for Retinal and Neuronal Degeneration in Drosophila melanogaster
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2023)Past work to understand the mechanisms of cellular degeneration has either focused on retinal degeneration or neurodegeneration. These studies have revealed that the integrated stress response (ISR) and RNA binding proteins ... -
Control of virulence gene transcription by indirect readout in Vibrio cholerae and Salmonella enterica serovar Typhimurium
(2017)Indirect readout mechanisms of transcription control rely on the recognition of DNA shape by transcription factors (TFs). TFs may also employ a direct readout mechanism that involves the reading of the base sequence in the ... -
DNA supercoiling and the Lrp protein determine the directionality of fim switch DNA inversion in Escherichia coli K-12
(2006)Site-specific recombinases of the integrase family usually require cofactors to impart directionality in the recombination reactions that they catalyze. The FimB integrase inverts the Escherichia coli fim switch (fimS) in ... -
Genetic and expression analysis of cattle identifies candidate genes in pathways responding to Trypanosoma congolense infection.
(2011)African bovine trypanosomiasis caused by Trypanosoma sp., is a major constraint on cattle productivity in sub-Saharan Africa. Some African Bos taurus breeds are highly tolerant of infection, but the potentially more ... -
Genetic structure and trait estimation in ancient Europeans
(Trinity College Dublin. School of Genetics & Microbiology. Discipline of Genetics, 2023)The study of ancient human populations have mostly been carried out, until recently, by historians through the study of written records and ancient manufacts. Thanks to recent technological and theoretical advancements in ... -
The immune evasion protein Sbi of Staphylococcus aureus occurs both extracellularly and anchored to the cell envelope by binding lipoteichoic acid
(2012)The Sbi protein of Staphylococcus aureus comprises two IgG binding domains similar to those of protein A and a region that triggers the activation of complement C3. Sbi is expressed on the cell surface but its C-terminal ... -
Nasal Colonisation by Staphylococcus aureus Depends upon Clumping Factor B Binding to the Squamous Epithelial Cell Envelope Protein Loricrin.
(2012)Staphylococcus aureus asymptomatically colonises the anterior nares, but the host and bacterial factors that facilitate colonisation remain incompletely understood. The S. aureus surface protein ClfB has been shown to ... -
Network rewiring: physiological consequences of reciprocally exchanging the physical locations and growth-phase-dependent expression patterns of the Salmonella fis and dps genes
(2020)The Fis nucleoid-associated protein controls the expression of a large and diverse regulon of genes in Gram-negative bacteria. Fis production is normally maximal in bacteria during the early exponential phase of batch ... -
A potential new pathway for Staphylococcus aureus dissemination: silent survival of S.aureus phagocytosed by human monocyte-derived macrophages.
(2008)Although considered to be an extracellular pathogen, Staphylococcus aureus is able to invade a variety of mammalian, non-professional phagocytes and can also survive engulfment by professional phagocytes such as neutrophils ... -
Prevention of autosomal dominant retinitis pigmentosa by systemic drug therapy targeting heat shock protein 90 (Hsp90)
(2010)Retinitis pigmentosa (RP) is the most prevalent cause of registered visual handicap among working aged populations of developed countries. Up to 40% of autosomal dominant cases of disease are caused by mutations within the ... -
Transplantation of syngeneic schwann cells to the retina of the rhodopsin knockout (Rho-/-) mouse
(The Association for Research in Vision and Ophthalmology, Inc., 2003)PURPOSE: To determine whether subretinal Schwann cell transplantation can prolong the survival of photoreceptors in the rhodopsin knockout (rho(-/-)) mouse. METHODS: Schwann cells were prepared from postnatal day (PN) 5 ...
