Kinases are critical enzymes that play a significant role in several cellular processes. They regulate the activity of proteins by adding phosphates to them and are involved in numerous signaling pathways. There are several synonyms for kinases, such as protein kinases, phosphotransferases, and phosphokinases. Other types of kinases include cyclin-dependent kinases, which are crucial in cell division, tyrosine kinases, which control the activity of receptors, and serine/threonine kinases, which regulate several cellular processes such as metabolism, survival, and differentiation. Understanding the various types of kinases is essential in developing targeted therapies for diseases like cancer and diabetes, where kinase activity is often dysregulated.
