molecular function
    GO:0070324    thyroid hormone binding    Interacting selectively and non-covalently with thyroxine (T4) or triiodothyronine (T3), tyrosine-based hormones produced by the thyroid gland.
biological process
    GO:0042572    retinol metabolic process    The chemical reactions and pathways involving retinol, one of the three compounds that makes up vitamin A.
    GO:0070327    thyroid hormone transport    The directed movement of thyroid hormone into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
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.
