Asymmetric/Biological Unit(hide GO term definitions)

Chain A (LACB_BOVIN | P02754)

molecular function
	GO:0019841	retinol binding	Interacting selectively and non-covalently with retinol, vitamin A1, 2,6,6-trimethyl-1-(9'-hydroxy-3',7'-dimethylnona-1',3',5',7'-tetraenyl)cyclohex-1-ene, one of the three components that makes up vitamin A. Retinol is an intermediate in the vision cycle and it also plays a role in growth and differentiation.
	GO:0036094	small molecule binding	Interacting selectively and non-covalently with a small molecule, any low molecular weight, monomeric, non-encoded molecule.
biological process
	GO:0006810	transport	The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
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.
