Active cytoplasmic RNA localization depends on the attachment of RNA-binding proteins that dictate the destination of the RNA molecule. In this study, we used an electrophoretic mobility-shift assay in combination with equilibrium and kinetic analyses to characterize the assembly of the human zipcode-binding protein IMP1 on targets in the 3'-UTR from Igf-II mRNA and in H19 RNA. In both cases, t...
The nuclear import of classical nuclear localization signal-containing proteins depends on importin-alpha transport receptors. In budding yeast there is a single importin-alpha gene and in higher eukaryotes there are multiple importin-alpha-like genes, but in fission yeast there are two: the previously characterized cut15 and the more recently identified imp1. Like other importin-alpha family m...
Chronic inflammation and associated pathways are significant facilitators of many disease states, including malignancies. In the context of cancer, fibroblasts can actively regulate both inflammation and carcinogenesis. In this issue, Hamilton and colleagues describe a fibroblast-specific role of the RNA binding protein Imp1 in suppression of intestinal inflammatory responses and development of...
The aim of these notes is to show how the magnetic calculus developed in [MP, IMP1, IMP2, MPR, LMR] permits to give a new information on the nature of the coefficients of the expansion of the trace of a function of the magnetic Schrödinger operator whose existence was established in [HR2].
The intramembrane proteolytic activities of presenilins (PSEN1/PS1 and PSEN2/PS2) underlie production of β-amyloid, the key process in Alzheimer's disease (AD). Dysregulation of presenilin-mediated signaling is linked to cancers. Inhibition of the γ-cleavage activities of PSENs that produce Aβ, but not the ε-like cleavage activity that release physiologically essential transcription activators,...
Overexpression of the oncofetal insulin-like growth factor 2 mRNA-binding protein 2 (IMP2/IGF2BP2) has been described in different cancer types. Gallbladder carcinoma (GBC) is a rare but highly aggressive cancer entity with late clinical detection and poor prognosis. The aim of this study was to investigate the role of IMP2 in human GBC. Tissue microarrays (TMAs) of an international multi-cente...
Localized mRNAs are transported to sites of local protein synthesis in large ribonucleoprotein (RNP) granules, but their molecular composition is incompletely understood. Insulin-like growth factor II mRNA-binding protein (IMP) zip code-binding proteins participate in mRNA localization, and in motile cells IMP-containing granules are dispersed around the nucleus and in cellular protrusions. We ...
