2. Enzyme activators
3. Receptor site binders
4. Receptor site blockers
Where do you find apoB100? (3)
Function?
VLDL, IDL, LDL
Structural protein for VLDL; ligand for LDL receptor
Where do you find apoB48?
Function (2)
Chylomicrons, chylomicron remnants
Function: structural protein of chylomicrons, lacks LDL-R binding domain and can't bind to LDL R
Where do you find apoE? (5)
Function?
Chylomicrons/remnants, VLDL, IDL, HDL
Ligand for binding IDL to LDL-R and LRP
Where do you find Apo A-1?
Function?
chylo, HDL
Structural protein of HDL, activates LCAT/PCAT (forms CE)
