Tan et al. identify the E3-ligase MARCH6 as an important regulator of endothelial sprouting angiogenesis, owing to its ability to degrade the cholesterol biosynthetic enzyme SQLE. The study highlights that adequate SQLE levels are a critical determinant of maintaining endothelial junctions and proper sprouting angiogenesis.
- adherens junction
- cholesterol metabolism
- endothelial barrier
- membrane organization
- post-transcriptional regulation
