Chain A (RET1_RAT | P02696)

molecular function
	GO:0008289	lipid binding	Interacting selectively and non-covalently with a lipid.
	GO:0016918	retinal binding	Interacting selectively and non-covalently with retinal, one of the forms of vitamin A. Retinal plays an important role in the visual process in most vertebrates, combining with opsins to form visual pigments in the retina.
	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:0005215	transporter activity	Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
biological process
	GO:0030852	regulation of granulocyte differentiation	Any process that modulates the frequency, rate or extent of granulocyte differentiation.
	GO:0033189	response to vitamin A	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a vitamin A stimulus.
	GO:0002138	retinoic acid biosynthetic process	The chemical reactions and pathways resulting in the biosynthesis of retinoic acid, one of the three components that makes up vitamin A.
	GO:0042573	retinoic acid metabolic process	The chemical reactions and pathways involving retinoic acid, one of the three components that makes up vitamin A.
	GO:0042572	retinol metabolic process	The chemical reactions and pathways involving retinol, one of the three compounds that makes up vitamin A.
	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.
	GO:0006776	vitamin A metabolic process	The chemical reactions and pathways involving any of the vitamin A compounds, retinol, retinal (retinaldehyde) and retinoic acid, all of which are derivatives of beta-carotene.
cellular component
	GO:0044297	cell body	The portion of a cell bearing surface projections such as axons, dendrites, cilia, or flagella that includes the nucleus, but excludes all cell projections.
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
