enzyme that transfers phosphate groups to tyrosine on proteins
Tyrosine Kinase (TK) is an enzyme that functions by transferring a phosphate group from ATP to a specific amino acid called tyrosine on a protein. This process, known as phosphorylation, is crucial for regulating various cellular activities, including cell division, growth, and signaling pathways. Dysregulation of tyrosine kinases can lead to diseases such as cancer, making them important targets for certain therapeutic drugs.
