NMR Structure(hide GO term definitions)
Chain A   (MER2_EUPRA | P26886)
molecular function
    GO:0000772    mating pheromone activity    The activity of binding to and activating specific cell surface receptors, thereby inducing a behavioral or physiological response(s) from a responding organism or cell that leads to the transfer or union of genetic material between organisms or cells. The mating pheromone can either be retained on the cell surface or secreted.
    GO:0005186    pheromone activity    The activity of binding to and activating specific cell surface receptors, thereby inducing behavioral, developmental, or physiological response(s) from a responding organism or cell. The substance may be released or retained on the cell surface. Pheromones may serve as a specific attractant, social communicator, or sexual stimulant.
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.
