Kinase, in vitro: 

An enzyme-substrate reaction that occurs in non-living experimental conditions such as a test tube. For example, a purified enzyme is reacted with a substrate protein or mixture of proteins or peptides.

ERK1 S142-p
ERK2 S142-p
Src Y406-p
 Putative in vivo kinases: 

An enzyme-substrate reaction that occurs within living cells; includes cultured cells, ex vivo samples, and intact organisms. In the case of kinases, the large number of protein kinases in intact cells makes exact identification of the responsible kinase challenging.

ERK1 S142-p
ERK2 S142-p
Src Y406-p
Treatment:
levothyroxine sodium S142-p
liothyronine Y406-p
SKI-606 Y406-p
