Examples of proteins in the cell membrane are pore/channel proteins, carriers, glycoproteins.
Therefore protein assist in transport of substances across cell membrane.
Cell recognition.
Involved in mechanical strength and attachment of the cell membrane ( protein substances surround the cell membrane that allows it to attach to other cells)
---- protective
regulate transport in and out of cell or subcellular domain
allow selective receptivity and signal transduction by providing transmembrane receptors that bind signaling molecules
1)Regulates materials that come in and out of a cell. Is selectively-permeable, meaning it allows certain molecules or substances to enter but keeps the others out, and vice versa.
2)Keeps the cell in shape, as well as the organelles and materials inside.
3)Helps protect the cell
There are 3 main ways that membrane proteins function. This ways are to offer protection to the cell, regulate materials that come in an out of the cell and provide energy for various cellular processes.
Proteins 'manufacture' most of the components that make up cell membranes, they can provide structure and support to the cell membrane, and they can become embedded in the cell membranes, helping to transport materials across the cell membrane.
Peripheral proteins can be found on either side of the lipid bilayer: inside the cell or outside the cell. Membrane proteins can function as enzymes to speed up chemical reactions, act as receptors for specific molecules, or transport materials across the cell membrane.
There are two types of proteins in the membranes: integral membrane proteins that are embedded deep within the membrane and extend into the cytoplasm and peripheral membrane proteins that are present only on the cell surface.
Proteins are functional as:
1. Receptors for ligands
2. Channels for ions
3. Pores for small molecules and ions
4. Gateways for larger molecules
5. Anchorage points for other proteins and chemical groups
Proteins in the cell membrane can help give rigidity and structure to the membrane, act as receptors for cell signaling, or help with cell-cell adhesion.
There are four functions of proteins within the cell membrane. The four functions of proteins are active transport, cell recognition, cell communications, and are used as enzymes in the cell membrane.
proteins
Most membrane functions are carried out by proteins. The cell membrane is important because it protects what is inside the cell from outside damage.
Receptors, Selective Channels and pores

There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.

Proteins are not primary components of cell membrane. The proteins on the cell membrane have special functions, like receptors and transporters.
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
The two major components of the cell membrane are the phospholipid bilayer and proteins.
Receptors, Selective Channels and pores
Phospholipids are the major component of cell membranes, but there are proteins, glycoproteins and cholesterol also in the membrane.
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.
Once the proteins are produced by the
Some molecules are too large to pass through the cell membrane without transport proteins.
