MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Chitinases catalyze the hydrolysis of chitin, which is an abundant glycopolymer found in insect exoskeletons and fungal cell walls. The glycoside hydrolase 18 family of chitinases includes eight human family members. This gene encodes a glycoprotein member of the glycosyl hydrolase 18 family. The protein lacks chitinase activity and is secreted by activated macrophages, chondrocytes, neutrophils and synovial cells. The protein is thought to play a role in the process of inflammation and tissue remodeling. [provided by RefSeq, Sep 2009]
PHENOTYPE: Homozygous null mice show impaired OVA-induced Th2 responses with reduced splenocyte proliferation, cytokine production and IgE levels, impaired dendritic cell recruitment, higher CD4 T cell, macrophage and eosinophil apoptosis, and reduced CD4 T cell and alternatively activated macrophage numbers.
