Protein that must be imported to the nucleus from the cytoplasm carry nuclear localization signals (NLS) that are bound by importins. An NLS is a sequence of amino acids that acts as a tag. WebNov 13, 2024 · These experiments show that cortical dynein can perform bulk cytoplasmic transport by gliding microtubules along the cell cortex and through the ring canals to the oocyte. We propose that the dynein-driven microtubule flow could serve as a novel mode of cargo transport for fast cytoplasmic transfer to support rapid oocyte growth.
