SnapShot: Subcellular mRNA Localization
Many cells localize mRNAs to discrete locations in the cytoplasm. Coupled to local translation, this process affords precise spatial and temporal control of protein function. This SnapShot provides an overview of the key events in subcellular mRNA localization and highlights recent progress in understanding how cytoskeletal motors orchestrate mRNA trafficking.
متن کاملMechanisms of Subcellular mRNA Localization
Localization of RNA is a widespread and efficient way to target gene products to a specific region of a cell or embryo. This strategy of posttranscriptional gene regulation utilizes a variety of distinct mechanisms to regulate the movement and anchoring of different transcripts.
متن کاملSubcellular localization of expansin mRNA in xylem cells.
Terminal differentiation of many vascular cells involves cell wall changes. Cells first elongate their primary wall, then lay down a lignified secondary wall, which is often followed by digestion of the primary wall. Expansins are wall proteins that regulate wall changes, but little is known about the specific functions of the many individual expansin isoforms. An in vitro cell culture of synch...
متن کاملProtein targeting to subcellular organelles via MRNA localization.
Cells have complex membranous organelles for the compartmentalization and the regulation of most intracellular processes. Organelle biogenesis and maintenance requires newly synthesized proteins, each of which needs to go from the ribosome translating its mRNA to the correct membrane for insertion or transclocation to an a organellar subcompartment. Decades of research have revealed how protein...
متن کاملSubcellular localization of mRNA and factors involved in translation initiation.
Both the process and synthesis of factors required for protein synthesis (or translation) account for a large proportion of cellular activity. In eukaryotes, the most complex and highly regulated phase of protein synthesis is that of initiation. For instance, across eukaryotes, at least 12 factors containing 22 or more proteins are involved, and there are several regulated steps. Recently, the ...
