The cell controls nuclear transport through various cellular signal pathways.
Understand the Problem
The question is asking about the mechanisms by which a cell regulates the transport of substances to and from the nucleus through specific signaling pathways.
Answer
Nuclear transport is controlled by pathways involving nuclear localization signals, transport receptors, protein kinases, and MAPK cascades.
The cell controls nuclear transport through cellular signal pathways chiefly by using nuclear localization signals and nuclear transport receptors. These receptors and pathways, including protein kinase signaling and MAPK cascades, regulate nucleocytoplasmic transport by modifying the transport proteins and signals involved.

The cell controls nuclear transport through cellular signal pathways chiefly by using nuclear localization signals and nuclear transport receptors. These receptors and pathways, including protein kinase signaling and MAPK cascades, regulate nucleocytoplasmic transport by modifying the transport proteins and signals involved.
More Information
Nuclear transport is vital for cellular functions, including the regulation of gene expression and response to cellular signals. Signal transduction pathways like MAPK regulate this by modifying the transport process in response to cellular conditions.
Tips
A common oversight is not considering the role of specific signaling molecules like kinases and their phosphorylation targets in nuclear transport.
