Glycoproteins and plasma membrane

Proteins can be bound to other compounds to form nucleoproteins, glycoproteins, and lipoproteins. Of particular interest are the glycoproteins associated with the plasma membrane of the cells that coat the membrane surface.

The membrane glycoproteins are crucial to the life of the cell, very possibly serving as the receptors for hormone, certain nutrients, and various other substances that influence cellular functions.

The glycoprotein surface coat is considered to be an integral part of the plasma membrane. These glycoproteins are played an important role in ion transport and intercellular communication.

Glycoproteins also help regulate the intracellular communications necessary for cell growth and tissue formation. Intracellular communication occurs through pathways that convert information from one part of a cell to another in response to external stimuli.
