And what it activates are molecules known as Mechs or simply Mech. So activate a wrap then goes on to activate protein kinases called Mech. So what exactly does Mech actually stand for? Well, it stands for Mitigation activated protein kinases and we have many different types. So what these activated Mechs do is they go on to activate further protein kinases so they go on to activate further processes, namely they go on to activate kinases we call Hercs or IRC. Now, ERC stands for extracellular signal regulated kinases.
