mRNA export is a critical cellular process that transports mature mRNA transcripts from the nucleus to the cytoplasm, enabling protein synthesis. This process involves a complex interplay of nuclear pore complexes, export receptors, and adaptor proteins ensuring that only properly processed mRNAs are exported.

Protein synthesis is the cellular process through which genetic information is translated into functional proteins, essential for cellular structure and function. It involves two main stages: transcription, where DNA is converted into mRNA, and translation, where mRNA is decoded by ribosomes to assemble amino acids into polypeptide chains.

Nuclear pore complexes (NPCs) are large protein assemblies that span the nuclear envelope, facilitating the regulated exchange of molecules between the nucleus and cytoplasm. They play a critical role in maintaining cellular function by controlling the transport of RNA, proteins, and other macromolecules, while also contributing to nuclear organization and genome regulation.

Adaptor proteins serve as critical intermediaries in cellular signaling pathways, linking receptor activation to downstream effector molecules. They do not possess intrinsic enzymatic activity but instead function by bringing together specific proteins to facilitate signal transduction.
