    GO ID   Ontology GO Term Definition
    6281   DNA Repair  The Process of Restoring DNA After Damage. Genomes Are Subject to Damage by Chemical and Physical Agents in the Environment (e.g. Uv and Ionizing Radiations Chemical Mutagens Fungal and Bacterial Toxins Etc.) and by Free Radicals or Alkylating Agents Endogenously Generated in Metabolism. DNA Is Also Damaged Because of Errors During Its Replication. a Variety of Different DNA Repair Pathways Have Been Reported That Include Direct Reversal Base Excision Repair Nucleotide Excision Repair Photoreactivation Bypass Double Strand Break Repair Pathway and Mismatch Repair Pathway. 
    6974   Cellular Response to DNA Damage Stimulus  Any Process That Results in a Change in State or Activity of a Cell (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Stimulus Indicating Damage to Its DNA From Environmental Insults or Errors During Metabolism. 
    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. 
    7067   Mitotic Nuclear Division  A Cell Cycle Process Comprising the Steps by Which the Nucleus of a Eukaryotic Cell Divides; the Process Involves Condensation of Chromosomal DNA Into a Highly Compacted Form. Canonically Mitosis Produces Two Daughter Nuclei Whose Chromosome Complement Is Identical to That of the Mother Cell. 
    7126   Meiotic Nuclear Division  One of the Two Nuclear Divisions That Occur As Part of the Meiotic Cell 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. 
    51301   Cell Division  The Process Resulting in the Physical Partitioning and Separation of a Cell Into Daughter Cells. 
    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. 
    5768   Endosome  A Membrane Bounded Organelle to Which Materials Ingested by Endocytosis Are Delivered. 
    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. 
    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. 
    15030   Cajal Body  A Class of Nuclear Body First Seen After Silver Staining by Ramon Y Cajal in 1903 Enriched in Small Nuclear Ribonucleoproteins and Certain General RNA Polymerase Ii Transcription Factors; Ultrastructurally They Appear As a Tangle of Coiled Electron Dense Threads Roughly 0.5 Micrometers in Diameter; Involved in Aspects of Snrnp Biogenesis; the Protein Coilin Serves As a Marker For Cajal Bodies. Some Argue That Cajal Bodies Are the Sites For Preassembly of Transcriptosomes Unitary Particles Involved in Transcription and Processing of Rna. 
    166   Nucleotide Binding  Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose. 
    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. 
    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. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
