What Are Kinase Inhibitors and Why Are They Important?
Kinases are enzymes that play an essential role in cellular processes such as growth, metabolism, apoptosis, and differentiation. These enzymes facilitate the addition of phosphate groups to proteins, a process known as phosphorylation. This process is critical for regulating many cellular activities, but when dysregulated, it can lead to various diseases, including cancer.
Kinase inhibitors are small molecules designed to interfere with the activity of specific kinases involved in disease processes. By selectively inhibiting the activity of these enzymes, kinase inhibitors can block the signaling pathways that drive the uncontrolled cell proliferation characteristic of cancer. Moreover, they can also modulate immune responses in autoimmune diseases, making them versatile therapeutic agents.
