Tyrosine kinases are enzymes that catalyze the transfer of phosphate groups from ATP to tyrosine residues in proteins. This phosphorylation event plays a crucial role in the regulation of various cellular processes, including cell growth, differentiation, and migration. Abnormal activation of tyrosine kinases has been associated with various diseases, including cancer, autoimmune disorders, and inflammatory diseases. As a result, tyrosine kinases have become a major target for drug development in the field of oncology and other therapeutic areas. Research in the field of tyrosine kinases focuses on understanding their mechanisms of action, identifying their substrate proteins, and developing targeted therapies that specifically inhibit their activity. This research has led to the development of several FDA-approved tyrosine kinase inhibitors that have shown clinical benefits in the treatment of various cancers and other diseases.
