Integral Proteins float freely within the bilayer of the cell membrane. They are usually transmembrane proteins, extending through the lipid bilayer. One end is in contact with the interior of the cell while the other remains in contact with the exterior. These are the only proteins that can perform functions both inside and outside the cell.
ion channel membrane proteins
There are many uses for proteins in a cell membrane but the most common ones are: 1. Facilitated diffusion- a protein acts almost like a channel to allow molecules that cannot fit across the phospholipid bilayer to diffuse into/out of the cell 2. Active transport- proteins are used to move particles across the membrane from low to high concentration, using energy. 3. As receptor molecules which take signals from things like hormones.
dendrite
Specific proetins can be detected by its specific mono clonal antibody. Primary antibodies specifically binds to the proetins on the membrane. Secondary antibody interact with primary antibody and signals its presence by chemiluminescence.
It sends signals between the cells external and internal environment.
Receptors are proteins on the cell membrane that are used to receive signals
ion channel membrane proteins
it receives signals and sends out signals

Antenna
Radiates and/or receives radio signals.
Dendrites
it receives it by signals

Actually all cells can send and receive signals. For example every cell has a CD95(FASr) which receives signals from natural killer cells or T cells and results in cell death. Also all cells send signals through cell membrane receptors to neighboring cells. These signals prevent neighboring cell colonies from growing too big.(The lack of these signals is one of the problems with certain cancer cells)
Yes, the cell membrane is actually what receives and recognizes different chemical signals, then it creates other chemicals to let a specific part of the cell to do something.
