So TF seven is basically this dimer protein complex that we form as soon as the rupturing process takes place. Now, once we form the TF seven complex, this dimer protein, this becomes acerine protease. And what that means is it goes on to activate other enzymes by cleaving them at specific amino acids on their amino acid sequence. Now, the TF seven complex has two different proteins that it readily activates. We have protein factor nine and protein factor ten. And notice that protein factor nine when it's activated, it goes on to activate some more of ten.
