Protein Receptor A protein receptor binds a hormone outside the cell membrane and activates protein kinase activity inside the cell. Is the receptor an intrinsic or extrinsic membrane protein.
Membrane receptors are extrinsic or associated with the surface of the bilayer.
Association with hormone results in a lipid signal released inside the cell to activate protein kinases. Membrane receptors associated with signaling are all intrinsic membrane proteins so that events on the cell surface can lead to subcellular signals. All rights reserved.
