WebTargeted disruption of SCAP in the cholesterol-rich organs of mice caused organ dysgenesis, although these models do not exhibit absolute lethality. Brains contain the highest levels of cholesterol in the body, and SCAP deletion in astrocytes showed microcephaly, without effects on astrocyte survival [ 16 ]. WebJan 24, 2024 · Bei hoher Cholesterinkonzentration löst Cholesterin eine Konformationsänderung von SCAP aus, sodass es an das Insig-Protein bindet. Dadurch wird SREBP nicht zum Golgi-Apparat transportiert und die Transkription für Gene der Cholesterinsynthese nimmt ab. cedar bluff united methodist church https://chrisandroy.com
