    GO ID   Ontology GO Term Definition
    6351   Transcription DNA Templated  The Cellular Synthesis of RNA On a Template of Dna. 
    6355   Regulation of Transcription DNA Templated  Any Process That Modulates the Frequency Rate or Extent of Cellular DNA Templated Transcription. 
    6915   Apoptotic Process  A Programmed Cell Death Process Which Begins When a Cell Receives an Internal (e.g. DNA Damage) or External Signal (e.g. an Extracellular Death Ligand) and Proceeds Through a Series of Biochemical Events (signaling Pathway Phase) Which Trigger an Execution Phase. the Execution Phase Is the Last Step of an Apoptotic Process and Is Typically Characterized by Rounding Up of the Cell Retraction of Pseudopodes Reduction of Cellular Volume (pyknosis) Chromatin Condensation Nuclear Fragmentation (karyorrhexis) Plasma Membrane Blebbing and Fragmentation of the Cell Into Apoptotic Bodies. When the Execution Phase Is Completed the Cell Has Died. 
    7049   Cell Cycle  The Progression of Biochemical and Morphological Phases and Events That Occur in a Cell During Successive Cell Replication or Nuclear Replication Events. Canonically the Cell Cycle Comprises the Replication and Segregation of Genetic Material Followed by the Division of the Cell But in Endocycles or Syncytial Cells Nuclear Replication or Nuclear Division May Not Be Followed by Cell Division. 
    16032   Viral Process  A Multi Organism Process in Which a Virus Is a Participant. the Other Participant Is the Host. Includes Infection of a Host Cell Replication of the Viral Genome and Assembly of Progeny Virus Particles. in Some Cases the Viral Genetic Material May Integrate Into the Host Genome and Only Subsequently Under Particular Circumstances 'complete' Its Life Cycle. 
    16310   Phosphorylation  The Process of Introducing a Phosphate Group Into a Molecule Usually with the Formation of a Phosphoric Ester a Phosphoric Anhydride or a Phosphoric Amide. 
    18107   Peptidyl Threonine Phosphorylation  The Phosphorylation of Peptidyl Threonine to Form Peptidyl O Phospho L Threonine. 
    31647   Regulation of Protein Stability  Any Process That Affects the Structure and Integrity of a Protein by Altering the Likelihood of Its Degradation or Aggregation. 
    5634   Nucleus  A Membrane Bounded Organelle of Eukaryotic Cells in Which Chromosomes Are Housed and Replicated. in Most Cells the Nucleus Contains All of the Cell's Chromosomes Except the Organellar Chromosomes and Is the Site of RNA Synthesis and Processing. in Some Species or in Specialized Cell Types RNA Metabolism or DNA Replication May Be Absent. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5815   Microtubule Organizing Center  An Intracellular Structure That Can Catalyze Gamma Tubulin Dependent Microtubule Nucleation and That Can Anchor Microtubules by Interacting with Their Minus Ends Plus Ends or Sides. 
    5819   Spindle  The Array of Microtubules and Associated Molecules That Forms Between Opposite Poles of a Eukaryotic Cell During Mitosis or Meiosis and Serves to Move the Duplicated Chromosomes Apart. 
    5856   Cytoskeleton  Any of the Various Filamentous Elements That Form the Internal Framework of Cells and Typically Remain After Treatment of the Cells with Mild Detergent to Remove Membrane Constituents and Soluble Components of the Cytoplasm. the Term Embraces Intermediate Filaments Microfilaments Microtubules the Microtrabecular Lattice and Other Structures Characterized by a Polymeric Filamentous Nature and Long Range Order Within the Cell. the Various Elements of the Cytoskeleton Not Only Serve in the Maintenance of Cellular Shape But Also Have Roles in Other Cellular Functions Including Cellular Movement Cell Division Endocytosis and Movement of Organelles. 
    72686   Mitotic Spindle  A Spindle That Forms As Part of Mitosis. Mitotic and Meiotic Spindles Contain Distinctive Complements of Proteins Associated with Microtubules.

    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    4674   Protein Serine/threonine Kinase Activity  Catalysis of the Reactions: ATP + Protein Serine = Adp + Protein Serine Phosphate and ATP + Protein Threonine = Adp + Protein Threonine Phosphate. 
    5515   Protein Binding  Interacting Selectively and Non Covalently with Any Protein or Protein Complex (a Complex of Two or More Proteins That May Include Other Nonprotein Molecules). 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    8353   RNA Polymerase Ii Carboxy Terminal Domain Kinase Activity  Catalysis of the Reaction: ATP + (dna Directed RNA Polymerase Ii) = Adp + Phospho (dna Directed RNA Polymerase Ii); Phosphorylation Occurs On Residues in the Carboxy Terminal Domain (ctd) Repeats. 
    16301   Kinase Activity  Catalysis of the Transfer of a Phosphate Group Usually From ATP to a Substrate Molecule. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2.
