Summaries for CHIA Gene

Entrez Gene Summary for CHIA Gene

  • The protein encoded by this gene degrades chitin, which is found in the cell wall of most fungi as well as in arthropods and some nematodes. The encoded protein can also stimulate interleukin 13 expression, and variations in this gene can lead to asthma susceptibility. Several transcript variants encoding a few different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

GeneCards Summary for CHIA Gene

CHIA (Chitinase, Acidic) is a Protein Coding gene. Diseases associated with CHIA include asthma and eumycotic mycetoma. Among its related pathways are Metabolism and Glycosaminoglycan metabolism. GO annotations related to this gene include carbohydrate binding and hydrolase activity, hydrolyzing O-glycosyl compounds. An important paralog of this gene is CHI3L2.

UniProtKB/Swiss-Prot for CHIA Gene

  • Degrades chitin and chitotriose. May participate in the defense against nematodes, fungi and other pathogens. Plays a role in T-helper cell type 2 (Th2) immune response. Contributes to the response to IL-13 and inflammation in response to IL-13. Stimulates chemokine production by pulmonary epithelial cells. Protects lung epithelial cells against apoptosis and promotes phosphorylation of AKT1. Its function in the inflammatory response and in protecting cells against apoptosis is inhibited by allosamidin, suggesting that the function of this protein depends on carbohydrate binding.
