WebNon-coding RNAs are emergent elements from the genome, which do not encode for proteins but have relevant cellular functions impacting almost all the physiological processes occurring in eukaryotic cells. In particular, microRNAs and long non-coding RNAs (lncRNAs) are a new class of small RNAs transcribed from the genome, which modulate the … Web18 feb. 2024 · We develop a computational model of cell growth and proteome increase, incorporating the kinetics of amino acid import, protein/ribosome synthesis and degradation, and active transport of proteins between the cytoplasm and the nucleoplasm. We also include a simple model of ribosome biogenesis and assembly.

Nucleocytoplasmic transport - PubMed

Nuclear transport refers to the mechanisms by which molecules move across the nuclear membrane of a cell. The entry and exit of large molecules from the cell nucleus is tightly controlled by the nuclear pore complexes (NPCs). Although small molecules can enter the nucleus without regulation, … Meer weergeven Protein that must be imported to the nucleus from the cytoplasm carry nuclear localization signals (NLS) that are bound by importins. An NLS is a sequence of amino acids that acts as a tag. They are most … Meer weergeven Many proteins are known to have both NESs and NLSs and thus shuttle constantly between the nucleus and the cytosol. In … Meer weergeven Nuclear export roughly reverses the import process; in the nucleus, the exportin binds the cargo and Ran-GTP and diffuses through the pore to the cytoplasm, where the complex dissociates. Ran-GTP binds GAP and hydrolyzes GTP, and the resulting … Meer weergeven • Nuclear Transport animations Archived 2009-02-07 at the Wayback Machine • Nuclear Transport illustrations Archived 2009-02-07 at the Wayback Machine Meer weergeven Web15 mrt. 1996 · Abstract Active transport of proteins and RNAs between the nucleus and cytoplasm is a major process in eukaryotic cells.
