1) Why don't all proteins with a ubiquitin chain get degraded by the proteasome? 2) What other outcomes might occur for a ubiquitin-tagged protein? 3) What are the basic structural, organizational, and functional features of the nucleus?
Added by Virginia H.
Step 1
Different chain linkages can lead to different outcomes, and only specific types of ubiquitin chains, such as the K48-linked chains, target proteins for proteasomal degradation. Show more…
