CC -!- FUNCTION: Carbohydrate-binding lectin with a preference for chitin. Has
CC no chitinase activity. May play a role in tissue remodeling and in the
CC capacity of cells to respond to and cope with changes in their
CC environment. Plays a role in T-helper cell type 2 (Th2) inflammatory
CC response and IL-13-induced inflammation, regulating allergen
CC sensitization, inflammatory cell apoptosis, dendritic cell accumulation
CC and M2 macrophage differentiation. Facilitates invasion of pathogenic
CC enteric bacteria into colonic mucosa and lymphoid organs. Mediates
CC activation of AKT1 signaling pathway and subsequent IL8 production in
CC colonic epithelial cells. Regulates antibacterial responses in lung by
CC contributing to macrophage bacterial killing, controlling bacterial
CC dissemination and augmenting host tolerance. Also regulates hyperoxia-
CC induced injury, inflammation and epithelial apoptosis in lung (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:12529329}.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space. Cytoplasm
CC {ECO:0000250}. Cytoplasm, perinuclear region {ECO:0000250}. Endoplasmic
CC reticulum {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 18 family. {ECO:0000305}.
CC -!- CAUTION: Although it belongs to the glycosyl hydrolase 18 family, Leu-
CC 140 is present instead of the conserved Glu which is an active site
CC residue. Therefore this protein lacks chitinase activity.
CC {ECO:0000305}.
