Artificial examples of these like Erbitux and Herceptin can be used to treat cancer.
Artificial examples of these like Erbitux and Herceptin can be used to treat cancer. The protein RAG-I is used to generate diversity in these structures via a process called VDJ recombination, and cells can change which type they produce via a process called class switching. These proteins, which share a "beta sheet sandwich" structure, activate complement via their Fc regions. The E type of these binds mast cells and mediates allergic responses, while the G type is the only one that can cross the placenta. They consist of heavy chains and light chains, and it is their variable regions that recognize and bind epitopes. For 10 points, name these proteins produced by B cells that bind antigens.
