How does a protein get accepted into its targeted cell? Does it have a special code or does it just know where to go?

Expert Solution

For a protein to be targeted, it should have a special code. A protein is produced by a pocess called translation in cytosol and it is transported to specific parts of the cells like nucleus, mitochondria, peroxisomes or chloroplast. As mentioned above, each protein has a special code consisting of certain set of amino acids which act as an address label to the protein. Each protein has specific targeting signal that are destined to specific cells organelles. For example, peroxisome targeting singal usually has three set of amino acids( serine, lysine, leucin). This set of amino acids is recognised by a helper protein in the cytosol and it transport the specific proteins to the peroxisome.

1. If glucose is phosphorylated upon entry, how does it get out of the epithelial cell? 2. Context: referring to the basic K+ and Na+ levels of a cell and how they move in and out of it. Both ions have a positive charge. K+ is more ubundant in the cell and Na+ is more outside. The inside of the cell is more naturally negative. If K+ is going out while Na+ is coming into the cell, why does the...

The chemotherapeutic monoclonal antibodies and protein kinase inhibitors are considered targeted forms of therapy. How do these two classes of chemotherapeutic agents specifically target cancer? In your answer describe the mechanism of action of Trastuzumab (Herceptin) and Imatinib (Gleevac), two targeted chemotherapeutic agents representing each class. Contrast the targeted mechanisms of action of these drugs to the cytotoxic chemotherapeutic agents.
