Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (GLUC_PIG | P01274)
molecular function
    GO:0031769    glucagon receptor binding    Interacting selectively and non-covalently with a glucagon receptor.
    GO:0005179    hormone activity    The action characteristic of a hormone, any substance formed in very small amounts in one specialized organ or group of cells and carried (sometimes in the bloodstream) to another organ or group of cells in the same organism, upon which it has a specific regulatory action. The term was originally applied to agents with a stimulatory physiological action in vertebrate animals (as opposed to a chalone, which has a depressant action). Usage is now extended to regulatory compounds in lower animals and plants, and to synthetic substances having comparable effects; all bind receptors and trigger some biological process.
biological process
    GO:0007188    adenylate cyclase-modulating G-protein coupled receptor signaling pathway    The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand, where the pathway proceeds through activation or inhibition of adenylyl cyclase activity and a subsequent change in the concentration of cyclic AMP (cAMP).
    GO:0043066    negative regulation of apoptotic process    Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.
    GO:0070374    positive regulation of ERK1 and ERK2 cascade    Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.
    GO:1903348    positive regulation of bicellular tight junction assembly    Any process that activates or increases the frequency, rate or extent of tight junction assembly.
    GO:0035774    positive regulation of insulin secretion involved in cellular response to glucose stimulus    Any process that increases the frequency, rate or extent of the regulated release of insulin that contributes to the response of a cell to glucose.
    GO:0010737    protein kinase A signaling    A series of reactions, mediated by the intracellular serine/threonine kinase protein kinase A, which occurs as a result of a single trigger reaction or compound.
    GO:0042594    response to starvation    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 starvation stimulus, deprivation of nourishment.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
