kinase
[C] Countable
pl: kinases
This term describes a biological switch. By adding a phosphate group to a protein, a kinase can effectively turn a protein on or off, altering its shape and function to trigger a cellular response. In medical and scientific contexts, the word carries a connotation of regulation and control. Dysregulation of kinases is a hallmark of many diseases, particularly cancer, making them primary targets for drug development and targeted therapies.
Used to refer to individual types of enzymes, such as a protein kinase or a hexokinase.
