A cholesterol-sensing mechanism unfolds [PDF]

Journal of Biological Chemistry, 2017
Squalene monooxygenase (SM), which synthesizes a cholesterol precursor, is degraded when cholesterol levels in the endoplasmic reticulum (ER) membrane are high, but the signal for degradation was not known. In this issue of JBC, Brown and co-workers identify an N-terminal domain in SM that interconverts in a cholesterol-sensitive manner between a ...
