Also known as CHIT2; AMCASE; TSA1902

Gene ID: 27159 | Gene type: protein coding

About CHIA

Cytogenetic location: 1p13.2 Genomic coordinates (GRCh38): 1:111,290,851-111,320,563 (from NCBI)

This gene has 10 transcripts (splice variants), 253 orthologues and 6 paralogues. Biased expression in stomach (RPKM 2.7), lung (RPKM 1.9) and 2 other tissues.

Summary

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]
