Tyk2

Tyk2 is a protein that plays a crucial role in the body's immune system by helping cells communicate and respond to signals from other parts of the immune system. It is a type of enzyme called a kinase, which adds small chemical groups to other proteins to activate or modify them. Tyk2 is involved in signaling pathways that help the body fight infections and regulate inflammation. When functioning properly, it supports healthy immune responses. However, if Tyk2 malfunctions or is blocked, it can impact immune activity, which is why it is sometimes targeted in treating autoimmune diseases or certain cancers.
