NMR Structure

(-) Gene Ontology  (6, 6)

NMR Structure(hide GO term definitions)
Chain A   (ERP27_HUMAN | Q96DN0)
molecular function
    GO:0005515    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).
    GO:0003756    protein disulfide isomerase activity    Catalysis of the rearrangement of both intrachain and interchain disulfide bonds in proteins.
biological process
    GO:0006457    protein folding    The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.
    GO:0034976    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.
cellular component
    GO:0005783    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).
    GO:0005788    endoplasmic reticulum lumen    The volume enclosed by the membranes of the endoplasmic reticulum.
