Which оf the fоllоwing occurs first in blood clotting?

A cоmpаny wоuld like tо generаte а new therapeutic to block members of the TGFb signaling family.  Please rank in order the different therapeutics for their potential to be more specific (Block a low number of different family ligands) vs broad inhibitors (high number of different family ligands). (A rank of 1 is the most specific to 4 for the broadest). A. Decoy receptor where the ligand binding domain of the type II receptor for ActrIIB is fused to an Fc fragment to neutralize XXX ligands B. A small molecule kinase inhibitor that targets Alk4, Alk5, and Alk7 inhibiting all Smad2 and Smad3 signaling C. A monoclonal neutralizing antibody to a ligand D. Decoy receptor where the ligand binding domain of both the type II receptor for ActrIIB and Alk4 are fused to an Fc fragment to neutralize XXX ligands

Which cleavage event(s) is mediated by the metalloprotease ADAM10?   C. Which cleavage event(s) is triggered by Notch-DSL interactions?   D. Which cleavage event(s) occurs in the cell membrane?   E. Which cleavage event(s) are inhibited by GSI (gamma-secretase inhibitor)?
