    Chain A
    GO ID   Ontology GO Term Definition
    79   Regulation of Cyclin Dependent Protein Serine/threonine Kinase Activity  Any Process That Modulates the Frequency Rate or Extent of Cyclin Dependent Protein Serine/threonine Kinase Activity. 
    1836   Release of Cytochrome C From Mitochondria  The Process That Results in the Movement of Cytochrome C From the Mitochondrial Intermembrane Space Into the Cytosol Which Is Part of the Apoptotic Signaling Pathway and Leads to Caspase Activation. 
    3334   Keratinocyte Development  The Process Whose Specific Outcome Is the Progression of a Keratinocyte Over Time From Its Formation to the Mature Structure. 
    6469   Negative Regulation of Protein Kinase Activity  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of Protein Kinase Activity. 
    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. 
    7165   Signal Transduction  The Cellular Process in Which a Signal Is Conveyed to Trigger a Change in the Activity or State of a Cell. Signal Transduction Begins with Reception of a Signal (e.g. a Ligand Binding to a Receptor or Receptor Activation by a Stimulus Such As Light) or For Signal Transduction in the Absence of Ligand Signal Withdrawal or the Activity of a Constitutively Active Receptor. Signal Transduction Ends with Regulation of a Downstream Cellular Process E.g. Regulation of Transcription or Regulation of a Metabolic Process. Signal Transduction Covers Signaling From Receptors Located On the Surface of the Cell and Signaling Via Molecules Located Within the Cell. For Signaling Between Cells Signal Transduction Is Restricted to Events At and Within the Receiving Cell. 
    8630   Intrinsic Apoptotic Signaling Pathway in Response to DNA Damage  A Series of Molecular Signals in Which an Intracellular Signal Is Conveyed to Trigger the Apoptotic Death of a Cell. the Pathway Is Induced by the Detection of DNA Damage and Ends When the Execution Phase of Apoptosis Is Triggered. 
    10482   Regulation of Epidermal Cell Division  Any Process That Modulates the Frequency Rate or Extent of the Physical Partitioning and Separation of an Epidermal Cell Into Daughter Cells. an Epidermal Cell Is Any of the Cells That Make Up the Epidermis. 
    10839   Negative Regulation of Keratinocyte Proliferation  Any Process That Decreases the Rate Frequency or Extent of Keratinocyte Proliferation. Keratinocyte Proliferation Is the Multiplication or Reproduction of Keratinocytes Resulting in the Expansion of a Cell Population.

    30307   Positive Regulation of Cell Growth  Any Process That Activates or Increases the Frequency Rate Extent or Direction of Cell Growth. 
    31424   Keratinization  The Process in Which the Cytoplasm of the Outermost Cells of the Vertebrate Epidermis Is Replaced by Keratin. Keratinization Occurs in the Stratum Corneum Feathers Hair Claws Nails Hooves and Horns.
