XPO1E571K Mutation Modifies Exportin 1 Localisation and Interactome in B-cell Lymphoma
2020
The XPO1 gene encodes exportin 1 (XPO1) that controls the nuclear export of cargo proteins and RNAs. Almost 25% of primary mediastinal B-cell lymphoma (PMBL) and classical Hodgkin lymphoma (cHL) cases harboured a recurrent XPO1 point mutation (NM_003400, chr2:g61718472C>
Cytoplasmic parvovirus capsids recruit importin beta for nuclear delivery
2020
Parvoviruses are an important platform for gene and cancer therapy. Their cell entry and the following steps including nuclear import are inefficient limiting their use in therapeutic applications. Two models exist on parvoviral nuclear entry: classical import of the viral capsid using nuclear transport receptors of the importin (karyopherin) family, or direct attachment of the capsid to the nuclear pore complex leading to local disintegration of the nuclear envelope. Here, by laser scanning confocal microscopy and in situ proximity ligation analysis combined with co-immunoprecipitation we showed that infection requires importin β-mediated access into the nuclear pore complex and nucleopori…
