Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (MER1_EUPRA | P10774)
molecular function
    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.
    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.
