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. And once we activate the Hercs, these Irks basically move on into the nucleus of our cell. And in the nucleus these Irks ultimately stimulate transcription factors to basically bind onto specific genes and express proteins. And the more proteins we're able to express, the quicker our cells can actually grow.
