Chain A   (SHBG_HUMAN | P04278)
molecular function
    GO:0005497    androgen binding    Interacting selectively and non-covalently with any androgen, male sex hormones.
    GO:0008289    lipid binding    Interacting selectively and non-covalently with a lipid.
    GO:0005496    steroid binding    Interacting selectively and non-covalently with a steroid, any of a large group of substances that have in common a ring system based on 1,2-cyclopentanoperhydrophenanthrene.
cellular component
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    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.
