Peripheral cell membrane proteins are:

There are two types of cell membrane proteins: Integral proteins - protrude all the way through the membrane Peripheral proteins - attached only to one surface of the membrane and do not penetrate all the way through. Integral proteins acts as: Channels carriers enzymes cell adhesion molecule Peripheral proteins acts as: Receptors cell adhesion molecules (CAMs) sub membranous cytoskeleton: ankyrin is a peripheral membrane protein that anchors the spectrin-actin meshwork directly to an integral membrane protein of the erythrocyte
