Chain A   (P2RY6_HUMAN | Q15077)
molecular function
    GO:0045028    G-protein coupled purinergic nucleotide receptor activity    Combining with a purine nucleotide and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex.
    GO:0004930    G-protein coupled receptor activity    Combining with an extracellular signal and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex.
    GO:0045029    UDP-activated nucleotide receptor activity    Combining with a nucleotide and transmitting the signal to a heterotrimeric G-protein complex to initiate a change in cell activity, activated by UDP.
    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:0004871    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.
biological process
    GO:0035589    G-protein coupled purinergic nucleotide receptor signaling pathway    The series of molecular signals generated as a consequence of a receptor binding to an extracellular purine nucleotide and transmitting the signal to a heterotrimeric G-protein complex to initiate a change in cell activity.
    GO:0007186    G-protein coupled receptor signaling pathway    A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).
    GO:0071407    cellular response to organic cyclic compound    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 an organic cyclic compound stimulus.
    GO:0071380    cellular response to prostaglandin E stimulus    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 prostagladin E stimulus.
    GO:0007200    phospholipase C-activating 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 with activation of phospholipase C (PLC) and a subsequent increase in the concentration of inositol trisphosphate (IP3) and diacylglycerol (DAG).
    GO:0014911    positive regulation of smooth muscle cell migration    Any process that activates, maintains or increases the frequency, rate or extent of smooth muscle cell migration.
    GO:0007165    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.
    GO:0030321    transepithelial chloride transport    The directed movement of chloride ions from one side of an epithelium to the other.
cellular component
    GO:0016324    apical plasma membrane    The region of the plasma membrane located at the apical end of the cell.
    GO:0016323    basolateral plasma membrane    The region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0005887    integral component of plasma membrane    The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
