Membrane proteins have many different functions; many are involved in transport across the cell membrane, such as channels, carriers and pumps (e.g .the Na/K-ATPase and P-glycoprotein), others are hormone receptors (e.g. EGFR and the insulin receptor) or confer structure to the cell membrane.

What are function of membrane proteins?
Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.
Is not a function of protein in a cell membrane?
Proteins are not primary components of cell membrane. The proteins on the cell membrane have special functions, like receptors and transporters.
What Molecules in the plasma membrane function as transporters?
Proteins
Is hormone reception a function of intergral membrane proteins?
Yes it is !
What is the function of proteins and carbohydrates that are embedded in a cell membrane?
They help control what enters and leaves the cells.
What are membrane structures that function in active transport?
integral proteins
Is protein sythesis a function made by the cell membrane?
No, the site of protein synthesis is the ribosomes, free and bound. The ribosome is the " workbench " on which proteins are made. Proteins can be imbedded in the membrane and can span the membrane.
What is the the function of proteins in the plasma membrane?
The proteins of the plasma serve the function of acting as porins. Porins are channels control the transport of substances in and out of the cell, imparting the membrane its property of semipermeabililty. Also, proteins make up 60-70% of the plasma membrane and thus form the bulk of it. Besides, the proteins are also involved in some important cellular reations.
What is the role of the membrane in the rough endoplasmic reticulum?
The membrane of the RER contains ribosomes. This is what makes the membrane "rough". The function of the ribosomes is to produce proteins.
What does a globular protein do in a cell membrane?
Globular proteins act as enzymes and catalyze organic reactions. They also transmit messages to regulate biological processes. Globular Proteins transport molecules through the membrane, and act as regulators within the membrane.
What structures in the cell membrane function as ion channels?
protein channels
What is the function of the peripheral protein?
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure. Proteins with GPI anchors are an exception to this rule and can have purification properties similar to those of integral membrane proteins.
