What are scaffolding proteins? what are scaffolding proteins? ladderlike proteins that allow receptor-ligand complexes to climb through cells from one position to another proteins that can reach into the nucleus of a cell to affect transcription microtubular protein arrays that allow lipid-soluble hormones to get from the cell membrane to the nuclear pores relay proteins that orient receptors and their ligands in appropriate directions to facilitate their complexing large molecules to which several relay proteins attach to facilitate cascade effects?
