RNA Transport Control Flashcards
What is mRNA localization?
mRNA that is localized in one particular location in the cytoplasm
Why is mRNA localization used to control gene expression?
Some mRNA and proteins need to be in a certain location in the cell to accomplish their functions, so moving them to that location increases expression
How does mRNA localization also keep the protein in a particular location?
mRNA localization also localizes translation
In which cells is mRNA localization typically found?
Early embryos, skin cells, neurons
Why is mRNA localization particularly important for embryonic development?
Some mRNA needs to be in the right place for certain structures to develop
How are mRNAs transported to the correct location in a cell?
Motor proteins along the cytoskeleton
How does the cell know where an mRNA is supposed to be localized?
Specific sequences in the 3’ UTR where proteins bind
