    Chain A
    GO ID   Ontology GO Term Definition
    6468   Protein Phosphorylation  The Process of Introducing a Phosphate Group On to a Protein. 
    4672   Protein Kinase Activity  Catalysis of the Phosphorylation of an Amino Acid Residue in a Protein Usually According to the Reaction: a Protein + ATP = a Phosphoprotein + Adp. 
    4707   Map Kinase Activity  Catalysis of the Reaction: Protein + ATP = Protein Phosphate + Adp. This Reaction Is the Phosphorylation of Proteins. Mitogen Activated Protein Kinase; a Family of Protein Kinases That Perform a Crucial Step in Relaying Signals From the Plasma Membrane to the Nucleus. They Are Activated by a Wide Range of Proliferation or Differentiation Inducing Signals; Activation Is Strong with Agonists Such As Polypeptide Growth Factors and Tumor Promoting Phorbol Esters But Weak (in Most Cell Backgrounds) by Stress Stimuli. 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    16772   Transferase Activity Transferring Phosphorus Containing Groups  Catalysis of the Transfer of a Phosphorus Containing Group From One Compound (donor) to Another (acceptor).
