Which of these actions occur(s) commonly at a nuclear pore complex? Choose one or more: Nuclear import receptors enter from the cytosol. Nuclear import receptors are exported to the cytosol. Proteins with a nuclear localization signal enter at the same time that proteins with a nuclear export signal exit. mRNA molecules are exported to the cytosol. Protein complexes diffuse into the nucleus. Small water-soluble molecules are selectively transported into the nucleus..
