Functions of Tyrosine Kinase
- Tyrosine kinases are proteins that catalyse the phosphorylation of tyrosine residues.
- Phosphorylation of tyrosine residues regulates several aspects of proteins, including enzyme activity, subcellular localization, and molecular interaction. Furthermore, tyrosine kinases participate in a variety of signal transduction cascades in which extracellular signals are transferred across the cell membrane to the cytoplasm and, in certain cases, to the nucleus, where gene expression is altered.
- Tyrosine kinases play important roles in a range of processes, routes, and activities in the body.
- Tyrosine kinase activity in the nucleus is associated with cell-cycle control and transcription factor characteristics.
Receptor Tyrosine Kinase Signaling
Cell signalling is a cell’s capacity to accept, process, and transmit messages to its surroundings and to itself. Cell signalling is a basic characteristic of all prokaryotic and eukaryotic cellular life. Extracellular signals (or signals that originate outside of a cell) can be physical agents such as mechanical pressure, electricity, temperature, light, or chemical signals (e.g., small molecules, peptides, or gas).
