    CHI3L1/YKL40 Background

    Gene Summary: Chitinases catalyze the hydrolysis of chitin, which is an abundant glycopolymer found in insect exoskeletons and fungal cell walls. The glycoside hydrolase 18 family of chitinases includes eight human family members. This CHI3L1 gene encodes a glycoprotein member of the glycosyl hydrolase 18 family. CHI3L1 protein lacks chitinase activity and is secreted by activated macrophages, chondrocytes, neutrophils and synovial cells. CHI3L1 is thought to play a role in the process of inflammation and tissue remodeling. [provided by RefSeq, Sep 2009]

    Subunit structure: Monomer. {ECO:0000269|PubMed:12775711, ECO:0000269|PubMed:12851408}.
    Subcellular location: Secreted, extracellular space {ECO:0000269|PubMed:9492324}. Cytoplasm {ECO:0000250}. Cytoplasm, perinuclear region {ECO:0000250}. Endoplasmic reticulum {ECO:0000250}.
    Tissue specificity: Present in activated macrophages, articular chondrocytes, synovial cells as well as in liver. Very low or undetectable expression in non-inflammatory colon. Undetectable in muscle tissues, lung, pancreas, mononuclear cells, or fibroblasts. {ECO:0000269|PubMed:16472595, ECO:0000269|PubMed:9492324}.
    Induction: Up-regulated in colon under several inflammatory conditions. Down-regulated by hyperoxia in bronchial epithelial cells. {ECO:0000269|PubMed:16472595, ECO:0000269|PubMed:20558631}.

    Involvement in disease: DISEASE: Asthma-related traits 7 (ASRT7) [MIM:611960]: Asthma-related traits include clinical symptoms of asthma, such as coughing, wheezing, dyspnea, bronchial hyperresponsiveness as assessed by methacholine challenge test, serum IgE levels, atopy and atopic dermatitis. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
    Sequence similarity: Belongs to the glycosyl hydrolase 18 family. {ECO:0000305}.
    General information above from UniProt

    Chitinase-3-like protein 1 (CHI3L1) is a secreted heparin-binding glycoprotein whose expression is associated with vascular smooth muscle cell migration. CHI3L1 is expressed at high levels in postconfluent nodular VSMC cultures and at low levels in subconfluent proliferating cultures. CHI3L1 is a tissue-restricted, chitin-binding lectin and member of glycosyl hydrolase family 18. In contrast to many other monocyto / macrophage markers, its expression is absent in monocytes and strong induced during late stages of human macrophage differentiation. Elevated levels of CHI3L1 are associated with disorders exhibiting increased connective tissue turnover, such as rheum atoid, arthritis, osteoarthritis, scleroderma, and cirrhosis of liver, but is produced in cartilage from old donors or patiens with osteoarthritis. CHI3L1 is abnormally expressed in the hippocampus of subjects with schizophrenia and may be involved in the cellular response to various environmental events that are reported to increase the risk of schizophrenia.
