NMR Structure(hide GO term definitions)
Chain A,B   (CVN_NOSEL | P81180)
molecular function
    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.
biological process
    GO:0050688    regulation of defense response to virus    Any process that modulates the frequency, rate or extent of the antiviral response of a cell or organism.
