Protein kinases are located on the plasma membrane as integral or peripheral membrane protein so that they can more readily encounter and phosphorylate other membranes proteins.
These protein are embedded in the phospholipid layer to perform the function of plasma membrane that mainly include the selective transport of molecules and cell - cell recognition.
The plasma membrane perform the function to provide protection for cell. It differentiate between the outside and inside of the cell.
Phospholipid is the lipid membrane that usually consist of lipid bilayers. It act as barrier to protect the cell against environmental issues.
