Cytoplasmic export
WebA nuclear export signal (NES) is a short target peptide containing 4 hydrophobic residues in a protein that targets it for export from the cell nucleus to the cytoplasm through the nuclear pore complex using nuclear transport.It has the opposite effect of a nuclear localization signal, which targets a protein located in the cytoplasm for import to the …

WebMar 20, 2015 · The RNA molecules that are exported from the nucleus into the cytoplasm include messenger RNAs (mRNAs), ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), small nuclear RNAs (snRNAs), micro RNAs (miRNAs), and viral mRNAs. Each RNA is transported by a specific nuclear export receptor. WebDec 17, 2015 · CRM1 is a highly conserved, RanGTPase-driven exportin that carries proteins and RNPs from the nucleus to the cytoplasm. We now explored the cargo-spectrum of CRM1 in depth and identified surprisingly large numbers, namely >700 export substrates from the yeast S. cerevisiae, ≈1000 from Xenopus oocytes and >1050 from …
WebOct 8, 2024 · Nuclear export of host mRNA that encodes antiviral factors is critical for antiviral protein production and control of viral replication. It is not surprising that several viruses have evolved sophisticated strategies to inhibit nuclear export of host mRNAs by targeting mRNA export pathways (10, 18).For example, nonstructural protein 1 (NS1) … National Center for Biotechnology Information
WebSep 2, 2005 · Like the Balbiani ring mRNAs, many mRNAs enter the translationally active pool immediately upon export to the cytoplasm. At this stage, the 5′ cap is still largely bound by the nuclear CBC20/80 complex, whereas the poly(A) tail carries a mixture of nuclear and cytoplasmic poly(A) binding proteins PABPN1 and PABPCs ( Table 1 ).

Creation of a nuclear export signal (NES) motif and loss of tryptophans (W) 288 and 290 (or 290 only) at the COOH terminus of nucleophosmin (NPM) are both crucial for NPM aberrant cytoplasmic accumulation in acute myelogenous leukemia (AML) carrying NPM1 mutations.
