Structural determinants of nuclear export signal orientation in binding to exportin CRM1

eLife, 2015
The Chromosome Region of Maintenance 1 (CRM1) protein mediates nuclear export of hundreds of proteins through recognition of their nuclear export signals (NESs), which are highly variable in sequence and structure.

Strength in Diversity: Nuclear Export of Viral RNAs

Viruses, 2020
The nuclear export of cellular mRNAs is a complex process that requires the orchestrated participation of many proteins that are recruited during the early steps of mRNA synthesis and processing.

Microguards and micromessengers of the genome [PDF]

, 2016
The regulation of gene expression is of fundamental importance to maintain organismal function and integrity and requires a multifaceted and highly ordered sequence of events.

TFIIA transcriptional activity is controlled by a ‘cleave-and-run’ Exportin-1/Taspase 1-switch [PDF]

Journal of Molecular Cell Biology, 2017
Transcription factor TFIIA is controlled by complex regulatory networks including proteolysis by the protease Taspase 1, though the full impact of cleavage remains elusive. Here, we demonstrate that in contrast to the general assumption, de novo produced TFIIA is rapidly confined to the cytoplasm via an evolutionary conserved nuclear export signal (NES,

Molecular medicine of microRNAs: structure, function and implications for diabetes [PDF]

, 2008
MicroRNAs (miRNAs) are a family of endogenous small noncoding RNA molecules, of 19–28 nucleotides in length. In humans, up to 3% of all genes are estimated to encode these evolutionarily conserved sequences.

Regulation of neutrophil senescence by microRNAs [PDF]

, 2011
Neutrophils are rapidly recruited to sites of tissue injury or infection, where they protect against invading pathogens. Neutrophil functions are limited by a process of neutrophil senescence, which renders the cells unable to respond to chemoattractants,

Exosomes promote pre-metastatic niche formation in ovarian cancer. [PDF]

, 2019
Ovarian cancer is one of the most common gynecological malignancies. Upon initial diagnosis, the majority of patients present with widespread metastatic growth within the peritoneal cavity. This metastatic growth occurs in stages, with the formation of a

microRNA. Diagnostic Perspective [PDF]

, 2015
Biomarkers are biological measures of a biological state. An ideal marker should be safe and easy to measure, cost efficient, modifiable with treatment, and consistent across gender and ethnic groups. To date, none of the available biomarkers satisfy all
