NMR Structure(hide GO term definitions)
Chain A   (CALC1_ONCKE | P01263)
molecular function
    GO:0031716    calcitonin receptor binding    Interacting selectively and non-covalently with a calcitonin 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:0007190    activation of adenylate cyclase activity    Any process that initiates the activity of the inactive enzyme adenylate cyclase.
    GO:0051482    positive regulation of cytosolic calcium ion concentration involved in phospholipase C-activating G-protein coupled signaling pathway    Any process that increases the concentration of calcium ions in the cytosol that occurs as part of a PLC-activating G-protein coupled receptor signaling pathway. G-protein-activated PLC hydrolyses phosphatidylinositol-bisphosphate (PIP2) to release diacylglycerol (DAG) and inositol trisphosphate (IP3). IP3 then binds to calcium release channels in the endoplasmic reticulum (ER) to trigger calcium ion release into the cytosol.
    GO:0048240    sperm capacitation    A process required for sperm to reach fertilization competence. Sperm undergo an incompletely understood series of morphological and molecular maturational processes, termed capacitation, involving, among other processes, protein tyrosine phosphorylation and increased intracellular calcium.
cellular component
    GO:0005623    cell    The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.
    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.
