Chain A (GRFIN_GRISQ | P84801)

molecular function
	GO:0046871	N-acetylgalactosamine binding	Interacting selectively and non-covalently with N-acetylgalactosamine, 2-acetamido-2-deoxygalactopyranose, the n-acetyl derivative of galactosamine.
	GO:0030246	carbohydrate binding	Interacting selectively and non-covalently with any carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates.
	GO:0005536	glucose binding	Interacting selectively and non-covalently with the D- or L-enantiomer of glucose.
	GO:0005537	mannose binding	Interacting selectively and non-covalently with mannose, a monosaccharide hexose, stereoisomeric with glucose, that occurs naturally only in polymerized forms called mannans.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
	GO:0008150	biological_process	Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end.
cellular component
	GO:0005623	cell	The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.
