The functions can vary greatly, the fact that its an integral protein limits the functions but there are still many different functions.
Ill go through a few functions of integral transmembrane proteins.
Transportation. Integral proteins can transport molecules and ions through the membrane, facilitated or active transport are two such transport functions. The protein can also act as ion channels which help the cells to keep the ion gradient at a good level (varies greatly for different ions). The protein can also act as receptors for different hormones or neural signals.
The integral proteins can also be cytoskelleton, which function is to connect different cells to eachother, or they can be flagells, villi or microvilli.

Functions of integral membrane protein?
Integral proteins are found within the membrane and have hydrophobic regions embedded within the membrane and hydrophilic regions that project from both surfaces of the bilayer Many integral proteins are glycoproteins, which have an attached carbohydrate chain. As with glycolipids, the carbohydrate chain of sugars projects externally. There- fore it can be said that the plasma membrane is "sugar- coated." The plasma membrane is asymmetrical: the two halves are not identical. The carbohydrate chains of the glyco-lipids and proteins occur only on the outside surface and the cytoskeletal filaments attach to proteins only on the inside surface
What is a type of protein found in the cell membrane which regulates the coming and going of substances into or out of the cell?
Membrane Protein
What is another name for integral proteins?
Integral proteins can be receptors, but not all integral proteins are. Therefore you cannot use the terms integral and receptor interchangeably. Integral proteins are proteins that are permanently attached to the membrane, and span the width (go from one side to the other). Receptor proteins are found on the surface of a cell and receive signals from other cells or the environment.
What proteins are on the surface of the cell membrane?
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).
What is a channel protein found in the thylakoid membrane that produces ATP from ADP and P?
ATP synthase complex
What are the two proteins found in the cell membrane?
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.

What kinds of proteins can be found in cell membranes?
Proteins found in cell membranes can include transport proteins, receptor proteins, cell adhesion proteins, and enzymes. These proteins play crucial roles in maintaining the structure and function of the cell membrane, as well as facilitating various biological processes such as cell signaling, molecule transport, and cell-cell interactions.

Membrane Protein
What molecules are responsible for special functions of cell membranes?
Cholesterol helps maintain membrane fluidity and stability, while glycolipids and glycoproteins are involved in cell recognition and communication. Integral proteins function as transporters, receptors, and channels, while peripheral proteins contribute to cell signaling and structural support. Together, these molecules play crucial roles in the special functions of cell membranes.

Where does the protein to make the plasma membrane?
that is found in a prokyotic cell
What are carrier proteins?
Carrier proteins are proteins that bind to specific molecules and transport them across cell membranes. They are essential for facilitating the movement of molecules like ions, nutrients, and signaling molecules in and out of cells. Carrier proteins exhibit selectivity and saturation kinetics in their binding and transport activities.
What is found in a membrane?
phospholipid biolayer is the membrane it self. the protein is what gets stick in the membrane. protein In context of unit membrane, it consists of a fluid mosaic of phosphoplipid bilayer and proteins. A phospholipid bilayer is made up of two layers of phospholipids with their non-polar tails facing away from the aqueous environment and polar heads towards the aqueous environment. They make up 40% of the membrane. Proteins make up 60% of the membrane and are of two types: 1. Integral proteins 2. Peripheral proteins There can also be presence of cholesterol molecules in the membrane in the hydrophobic region.
What protein classes are not found as membrane proteins - identity markers or receptors or transport channels or enzymes or hormones?
Enzymes and hormones are protein classes that are not typically found as membrane proteins acting as identity markers, receptors, or transport channels. Enzymes catalyze chemical reactions inside cells, while hormones are signaling molecules released into the bloodstream to regulate various physiological processes.
What would be found in the glomerular filtrate if the glomerular membrane were damaged?
protein
