There are two main roles of the membrane proteins. Membrane proteins act as channels across the lipid bilayer. They also act as carrier molecules that transfer substances across the membrane.
carrier proteins and channel proteins
Some membrane proteins are receptors for hormones or other chemicals. Some membrane proteins perform active transport of substances into or out of the cell.

The plasma membrane is flexible and is made up of organic molecules called lipids and proteins .
There are two types of proteins that are embedded in phospholipid membranes, extrinsic and intrinsic. Extrinsic proteins are only partially embedded in the membrane. They aid the structural stability of the membrane and when in conjunction with glycolipids can be involved in cell recognition. Intrinsic proteins pass all the way through a membrane. Some of them may be channel proteins which act as passages through the membrane for some molecules and ions.
The cell membrane contains many integral membrane proteins (proteins permanently attached to the surface), over the entire of its surface. These may include integrins, cadherins, desmosomes, clathrin-coated pits, caveolaes, and different structures involved in cell adhesion (the binding of a cell to the membrane surface).
The two main proteins found in the cell membrane are integral proteins and peripheral proteins. Integral proteins are embedded within the membrane and can span across it, while peripheral proteins are located on the surface of the membrane and are not embedded within it. Both types of proteins play important roles in various cellular functions including transport, communication, and cell signaling.
The two main functions of the proteins found in the plasma membrane are transport and inter-cellular communication. There are so many other roles that proteins play in the cell.
Some membrane proteins are receptors for hormones or other chemicals. Some membrane proteins perform active transport of substances into or out of the cell.
Membrane proteins relay signals between the cell's internal and external environments. They transport proteins and move molecules and ions across the membrane. They have many activities such as oxidoreductase, hydrolase or transferase.
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.
Intrinsic proteins are the integral proteins inside the plasma membrane, or phospholipid bilayer, of a cell. The reason they are called intrinsic is because they cannot be released unless the membrane is disrupted.

Membrane proteins and all other proteins are produced in cytoplasm. The proteins targeted to membranes by specific signals. Golgi vesicles transport the proteins to membrane. Not all proteins are membrane proteins
Anabolism of proteins is NOT an essential role of salts. Roles include: Controlling fluid movements, Excitabilty, Secretory activity, and membrane permeabilty.
Surprisingly, membrane proteins are found in or attached to the membrane.
The proteinshave certain 'identifiers' attached to them, which only allow certain particles through, making it selectively permeable.
