What are scaffolding proteins?
A) ladderlike proteins that allow receptor-ligand complexes to climb through cells from one position to another
B) microtubular protein arrays that allow lipid-soluble hormones to get from the cell membrane to the nuclear pores
C) large molecules to which several relay proteins attach to facilitate cascade effects
D) relay proteins that orient receptors and their ligands in appropriate directions to facilitate their complexing
E) proteins that can reach into the nucleus of a cell to affect transcription
Transmembrane proteins
The cell membrane is a lipid bilayer with signal proteins and channel proteins embedded in it.
Receptor-mediated endocytosis of LDL
In the retina, there are two types of light receptor cells: Rods are sensitive to differences in lig
Proteins can have several levels of structure
Misfolding or refolding of some proteins can result in disease
