Self-oligomerization regulates stability of survival motor neuron protein isoforms by sequestering an SCFSlmb degron

Authors:

Abstract
SMN protein levels inversely correlate with the severity of spinal muscular atrophy. The SCFSlmbE3 ligase complex interacts with a degron embedded within the C-terminal self-oligomerization domain of SMN. The findings elucidate a model whereby accessibility of the SMN degron is regulated by self-multimerization.
