Intracellular Compartments and Protein Sorting

Cell is the basic unit of life. Cell exists in either prokaryotic or eukaryotic forms. Both the cells are different from each other in structure and function. A bacterium that generally consists of only intracellular compartment covered by a plasma membrane, is an example of prokaryotic cell whereas on the other side eucaryotic cell have membraned compartments that are functionally distinct and have enzymes of its own. It is necessary to study the structure and dynamics of these compartments of cell and role of protein trafficking in order to understand the cytology. These specific proteins confer upon each compartments their defined structural and functional properties. These protein beside acting as organelle specific surface markers, also catalases the various reactions inside the cell and transports biomolecule selectively into and out of the cell.
