What is fusion protein

A fusion protein is a protein that is formed by the combination of two or more proteins, usually through genetic engineering techniques. The fusion protein can have new or enhanced functions that are not present in the individual proteins, making it useful in biotechnology and medical research. The fusion protein can also be used as a therapeutic agent to treat diseases such as cancer and autoimmune disorders. Examples of fusion proteins include green fluorescent protein (GFP) and antibody-drug conjugates (ADCs)
