Figure 7. The CSN3 subunit plays multiple roles in auxin signaling.

Figure 7

We hypothesize that in addition to its role in the CSN as a cullin deneddylase, the CSN3 subunit also regulates auxin signaling independently of the SCFTIR1/AFB ubiquitin-ligase. This second regulatory mechanism may involve the small CSN3-containing complex whose assembly is disrupted by the csn3-3 point mutation.
