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]
CHIA (Chitinase Acidic) is a Protein Coding gene. Diseases associated with CHIA include Asthma and Gaucher Disease, Type I. Among its related pathways are Metabolism and Glycosaminoglycan metabolism. Gene Ontology (GO) annotations related to this gene include carbohydrate binding and hydrolase activity, hydrolyzing O-glycosyl compounds. An important paralog of this gene is CHIT1.
