We have the leezing hormone and the follicle stimulating hormone, which are also examples of glycoproteins that act as hormones. Now, let's move on to tissue factor and antibodies. So we're not going to go into detail into these two glycoproteins because we actually focus on them in detail previously. So tissue factor is a glycoprotein that is basically exposed when the blood vessels in our cardiovascular system experience some type of trauma. And these glycoproteins, the tissue factor, is found on the membrane of epithelial cells and once the tissue factor, the glycoprotein, is exposed, it initiates the extrinsic pathway of the blood clotting cascade. It basically initiates the formation of blood clots, the coagulation process.
