CHIT1 (chitinase 1) gene is localized to human chromosome 1. This protein is highly expressed in cells of innate immune system, especially on activated macrophages. It is also known as chitotriosidase. In humans, it is expressed in lachrymal glands and lungs. This protein is a member of the 18 member human chitinase family.
Synonyms: Anti-Chitinase-1 antibody produced in rabbit; Anti-Chitotriosidase-1 precursor antibody produced in rabbit
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: CHIT1 (chitinase 1) enzyme prevents the growth of chitin-producing fungi such as, Candida albicans, Aspergillus niger and Cryptococcus neoformans. However, in human population, various dysfunctional mutations are found in this gene with no connected phenotypes, suggesting this protein is partially functionally redundant. The serum level of this protein is elevated during fungal infections and Gaucher's disease. Elevated serum levels of this protein are linked with resistance to airway obstruction in New York City firefighters, after exposure to WTC (world trade center)-particulate matter. In type II diabetes patients, the serum concentration of this protein increases progressively with the degree of albuminuria, and hence, is linked with diabetic vascular complications and kidney dysfunction.
