    GO ID   Ontology GO Term Definition
    6457   Protein Folding  The Process of Assisting in the Covalent and Noncovalent Assembly of Single Chain Polypeptides or Multisubunit Complexes Into the Correct Tertiary Structure. 
    34976   Response to Endoplasmic Reticulum Stress  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 Stress Acting At the Endoplasmic Reticulum. Er Stress Usually Results From the Accumulation of Unfolded or Misfolded Proteins in the Er Lumen. 
    5783   Endoplasmic Reticulum  The Irregular Network of Unit Membranes Visible Only by Electron Microscopy That Occurs in the Cytoplasm of Many Eukaryotic Cells. the Membranes Form a Complex Meshwork of Tubular Channels Which Are Often Expanded Into Slitlike Cavities Called Cisternae. the Er Takes Two Forms Rough (or Granular) with Ribosomes Adhering to the Outer Surface and Smooth (with No Ribosomes Attached). 
    5788   Endoplasmic Reticulum Lumen  The Volume Enclosed by the Membranes of the Endoplasmic Reticulum. 
    9986   Cell Surface  The External Part of the Cell Wall And/or Plasma Membrane. 
    3756   Protein Disulfide Isomerase Activity  Catalysis of the Rearrangement of Both Intrachain and Interchain Disulfide Bonds in Proteins. 
    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).
