mRNA needs to be assisted across the NPC. Like protein, also classed as facilitated diffusion. * mRNP exporter combines with mRNA with poly A tail, by interacting with FG repeats * mRNA moves through NPC * Dpb5 is an RNA helicase * Straightens the mRNA secondary structure and allows passage, removes proteins on the strand (NXT1, NXF1) * mRNP exporter proteins dissociate from the mRNA. * mRNA is now in cytoplasm

Microfilaments are also known as actin filaments; which, are protein filaments that are within the cytoplasm that form part of the cytoskeleton of an Eukaryotic Cell. They help in the process of cell movement via the actin working with another protein myosin that create muscle movements, cytoplasmic streaming, and cell division.
