tRNAs promote nuclear import of HIV-1 intracellular reverse transcription complexes [PDF]
Infection of non-dividing cells is a biological property of HIV-1 crucial for virus transmission and AIDS pathogenesis. This property depends on nuclear import of the intracellular reverse transcription and pre-integration complexes (RTCs/PICs).

Model system to study classical nuclear export signals [PDF]
Signal-mediated protein transport through the nuclear pore complex is of considerable interest in the field of molecular pharmaceutics. Nuclear localization signals can be used to target genes/antisense delivery systems to the nucleus. Studying nuclear export is useful in enhancing the expression and the efficiency of action of these therapeutic agents.

RNA export factor Ddx19 is required for nuclear import of the SRF coactivator MKL1 [PDF]
Controlled transport of macromolecules between the cytoplasm and nucleus is essential for homeostatic regulation of cellular functions. For instance, gene expression entails coordinated nuclear import of transcriptional regulators to activate ...

Active nuclear import and passive nuclear export are the primary determinants of TDP-43 localization
ALS (Amyotrophic Lateral Sclerosis) is a neurodegenerative disease characterized by the redistribution of the RNA binding protein TDP-43 in affected neurons: from predominantly nuclear to aggregated in the cytosol.

Huntingtin contains a highly conserved nuclear export signal [PDF]
Huntington's disease (HD), is a genetic neurodegenerative disease characterized by a DNA CAG triplet repeat expansion in the first exon of the disease gene, HD. CAG DNA expansion results in a polyglutamine tract expansion in mutant huntingtin protein. Wild-type and mutant full-length huntingtin have been detected in the nucleus, but elevated levels of ...

Nuclear phosphoinositide signaling regulates messenger RNA export [PDF]
Messenger RNA export from the nucleus to the cytoplasm plays an essential role in linking transcription to translation and consequently regulation of protein expression. mRNA export requires a series of events: pre-mRNA processing, ribonucleoprotein targeting to the NPC (nuclear pore complexes), and translocation through nuclear pores to the cytoplasm.

Structural and biochemical analysis of a B12 superbinder
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

The plasmodium export element revisited [PDF]
We performed a bioinformatical analysis of protein export elements (PEXEL) in the putative proteome of the malaria parasite Plasmodium falciparum. A protein family-specific conservation of physicochemical residue profiles was found for PEXEL-flanking ...
