ZAP-70 protein

ZAP-70 is a protein found inside certain immune cells called T-cells. It plays a crucial role in helping these cells recognize and respond to harmful invaders like viruses or bacteria. When a T-cell encounters an invader, ZAP-70 helps transmit signals that activate the cell, leading to an immune response. Proper functioning of ZAP-70 is essential for effective immune defense, and abnormalities in this protein can impact immune system activity, sometimes contributing to immune deficiencies or certain types of blood cancers.
