Addtional InformationFUNCTION:This protein might function as a defense against chitin containing pathogens. Binds to several branched or linear N- acetyllactosamine-containing glycosphingolipids and also to lactosylceramide with sphingosine and non-hydroxy fatty acids.SUBUNIT:Homodimer (Probable).PTM:Heavily glycosylated with beta-arabinose on hydroxyprolines and with alpha-galactose on serines of the extensin-like domain.As no other sugars could be detected in the native lectin, it is unlikely that the three putative N-glycosylation sites are actually glycosylated.PTM:The N-terminus is blocked. The N-terminal sequences proposed in PubMed:9022287 and PubMed:11056399 originate probably from truncated proteins.SIMILARITY:In the central section; belongs to the extensin family.SIMILARITY:Contains 4 chitin-binding type-1 domains.
