dc.description.abstract | RNA-binding proteins play crucial roles in RNA biogenesis and regulate the functions of all RNA species. Among these, RNA helicases form a unique class, altering RNA structures to influence the fate of cytoplasmic mRNA. DEAD-box (DDX) RNA helicases, in particular, have garnered significant attention in recent years due to their ability to unwind double-stranded RNA in an ATP-dependent manner. These helicases are also prominent components of RNA granules, such as stress granules and germ granules. Notably, members of the DDX3 family have been shown to form liquid-liquid phase-separated (LLPS) droplets in vitro, establishing them as a key model for studying RNA granule dynamics. This study explores the biophysical properties and molecular functions of LAF-1, the C. elegans ortholog of DDX3, with a particular focus on its role as a germ granule component. | eng |
dc.description.abstract | RNA-bindende Proteine spielen eine zentrale Rolle in der RNA-Biogenese und sind an der Regulation aller RNA-Spezies beteiligt. Zu diesen Proteinen gehören RNA-Helikasen, die eine einzigartige Klasse darstellen, weil sie RNA-Strukturen verändern und dadurch das Schicksal von zytoplasmatischer mRNA beeinflussen. Besonders DEAD-Box (DDX) RNA-Helikasen haben in den letzten Jahren verstärkt an Bedeutung gewonnen, da sie in der Lage sind, doppelsträngige RNA in einem ATP-abhängigen Prozess zu entwinden. Sie sind auch in RNA-Granula wie Stress- und Keimgranula vertreten. DDX3-Helikasen sind von besonderem Interesse, da sie in vitro durch Phasentrennung (LLPS) Tropfen bilden, was sie zu einem idealen Modell für die Erforschung der Dynamik von RNA-Granula macht. Diese Arbeit untersucht die biophysikalischen Eigenschaften und molekularen Funktionen von LAF-1, dem DDX3-Ortholog von C. elegans, mit besonderem Fokus auf seine Rolle als Bestandteil von Keimgranula. | ger |
