    Chain A
    GO ID   Ontology GO Term Definition
    6355   Regulation of Transcription DNA Templated  Any Process That Modulates the Frequency Rate or Extent of Cellular DNA Templated Transcription. 
    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. 
    7602   Phototransduction  The Sequence of Reactions Within a Cell Required to Convert Absorbed Photons Into a Molecular Signal. 
    18298   Protein Chromophore Linkage  The Covalent or Noncovalent Attachment of a Chromophore to a Protein. 
    50896   Response to Stimulus  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Stimulus. the Process Begins with Detection of the Stimulus and Ends with a Change in State or Activity or the Cell or Organism. 
    4871   Signal Transducer Activity  Conveys a Signal Across a Cell to Trigger a Change in Cell Function or State. a Signal Is a Physical Entity or Change in State That Is Used to Transfer Information in Order to Trigger a Response. 
    9881   Photoreceptor Activity  The Function of Absorbing and Responding to Incidental Electromagnetic Radiation Particularly Visible Light. the Response May Involve a Change in Conformation.
