Cytoplasmic translational initiation
Weband translation, where it is thought to bind co-tran-scriptionally to nascent transcripts and promote nuclear export. It was proposed that, once in the cytoplasm, it stimulates translation initiation and subsequent deadenylation and mRNA decay.10,11 Moreover, we showed that Rpb4/7 plays a key role in modulating Rpb1-CTD phosphorylation. WebThe systemic vasculitides are multifocal diseases characterized by the presence of blood vessel inflammation in multiple organ systems. Their clinical presentation is variable extending from self-limited illness to critical complications including diffuse alveolar hemorrhage and glomerulonephritis. Alveolar hemorrhage is a lifethreatening …

WebInitiation [ edit] The process of initiation of translation in eukaryotes. Translation initiation is the process by which the ribosome and its associated factors bind to an mRNA and are assembled at the start codon. This process is defined as either cap-dependent, in which the ribosome binds initially at the 5' cap and then travels to the stop ... WebThe eukaryotic translation initiation factor eIF4E is dysregulated in hematological malignancies including AML (Topisirovic et al, 2003; Assouline et al, 2009, 2015). eIF4E can be found in the nucleus and in the cytoplasm where it plays distinct roles in RNA metabolism, which contribute to AML and other malignancies (Cohen et al, ...

WebApr 24, 2015 · Overview of the steps of translation initiation in the cytoplasm of plants. Once the mRNA has been exported from the nucleus into the cytoplasm it interacts with a cap-binding complex (eIF4F or plant-specific eIFiso4F) at the 5′ end and PABP at the 3′ end. Additional factors, eIF4A and eIF4B are recruited to the mRNA to promote ATP ...
