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

Question

Quizplus · Accepted Answer

Scaffolding proteins are large molecules to which several relay proteins attach to facilitate cascade effects. They act as a framework upon which signaling proteins assemble, allowing for more efficient and precise signaling within the cell.
