Tyrosine Kinases

Tyrosine kinases are enzymes that add a phosphate group to tyrosine residues on proteins, resulting in a conformational change in the protein structure, which leads to activation of various signaling pathways. They are particularly important in regulating cell proliferation and differentiation, and are involved in the development of many diseases. Tyrosine kinase inhibitors have been developed as a class of therapeutic drugs, targeting and blocking protein tyrosine kinase activity and thus preventing inappropriate cell growth and division. These drugs are used to treat a wide range of disorders, including cancer, autoimmune disorders, and cardiovascular and metabolic diseases.
