Chain A,B,C,D (Q9PTT3_SPAAU | Q9PTT3)

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.
