What proteins are on the surface of the cell membrane?

Answer 1

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).

Answer 2

The peripheral proteins are stuck to the inside or the outside, while the integral proteins cut all the way through. There are two types of integral proteins: Channel proteins, which have a hole in the center for facilitated diffusion, and receptor protein.

Answer 3

A cell controls what moves through the membrane by means of membrane proteins within in the phospholipid bilayer. Some membrane proteins have carbohydrates attached to them, forming glycoproteins, that act as identification markers. We call these self proteins and they identify that cell belongs to the body and should not be attacked as an enemy. These are found on the surface or face of the cell. Other proteins include the cytoskeletal proteins spectrin and actin in erythrocytes and the enzyme protein kinase.

Answer 4

Proteins that stick into the cellmembrain.

Answer 5

According to the fluid mosaic model, proteins 'float' within the phospholipid bilayer of a cell membrane.

Answer 6

Integral proteins
