ID CHIA_RAT Reviewed; 473 AA. AC Q6RY07; DT 16-AUG-2004, integrated into UniProtKB/Swiss-Prot. DT 05-JUL-2004, sequence version 1. DT 16-NOV-2011, entry version 69. DE RecName: Full=Acidic mammalian chitinase; DE Short=AMCase; DE EC=3.2.1.14; DE Flags: Precursor; GN Name=Chia; OS Rattus norvegicus (Rat). OC Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; OC Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Sciurognathi; OC Muroidea; Muridae; Murinae; Rattus. OX NCBI_TaxID=10116; RN [1] RP NUCLEOTIDE SEQUENCE [MRNA]. RC STRAIN=Sprague-Dawley; TISSUE=Stomach; RA Chen X.-H., Cai G.-P.; RT "Rattus norvegicus similar to acidic mammalian chitinase precursor."; RL Submitted (NOV-2003) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Degrades chitin and chitotriose. May participate in the CC defense against nematodes, fungi and other pathogens. Plays a role CC in T helper cell type 2 (Th2) immune response. Contributes to the CC response to IL-13 and inflammation in response to IL-13. CC Stimulates chemokine production by pulmonary epithelial cells. CC Protects lung epithelial cells against apoptosis and promotes CC phosphorylation of AKT1. Its function in the inflammatory response CC and in protecting cells against apoptosis is inhibited by CC allosamidin, suggesting that the function of this protein depends CC on carbohydrate binding (By similarity). CC -!- CATALYTIC ACTIVITY: Random hydrolysis of N-acetyl-beta-D- CC glucosaminide (1->4)-beta-linkages in chitin and chitodextrins. CC -!- SUBUNIT: Interacts with EGFR (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). Secreted (By CC similarity). CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 18 family. Chitinase CC class II subfamily. CC -!- SIMILARITY: Contains 1 chitin-binding type-2 domain.
