The process of protein sorting Correct Answer-1. transport through nuclear pores 2. Across membranes 3. Transport through vesicles Signal Sequences Correct Answer-Direct a protein Transport to the nucleus Correct Answer-- nuclear pores - ~30kDa can go through by diffusion - unstructured protein loops fill it Nuclear Localization Signal (NLS) Correct Answer-A short amino acid sequence that marks a protein for delivery to the nucleus. drives nuclear transport Correct Answer-GTP hyd...

four main pathways for protein sorting Correct Answer-1. cytosolic proteins are simply synthesized in the cytosol 2. proteins destined for peroxisomes, mitochondria, and chloroplasts and synthesized in the cytosol and transported across membranes into the organelles 3. proteins destined for the nucleus are synthesized in the cytosol and transported thru nuclear pores 4. proteins destined for the ER, Golgi, endosomes, plasma membrane, and secretion are synthesized on the ER by the secretory pa...
