The protein encoded by this gene is similar to bacterial chitinases but lacks chitinase activity. The encoded protein is secreted and is involved in cartilage biogenesis. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
A study in humans demonstrated that the CHI3L2 exhibited increased polyadenylation in whole blood from patients with viral sepsis compared to those with bacterial infection, identifying it as a candidate post-transcriptional biomarker for distinguishing infection types [He et al. DOI: 10.1186/s12879-025-11078-z]. In a separate human study, the CHI3L2 was identified as part of a macrophage and microglial signature in the brain tissue of sepsis patients, though this specific association was not experimentally investigated in that cohort [Pinheiro da Silva et al. DOI: 10.1111/jcmm.17938]. A study in mice demonstrated that the CHI3L2 is expressed in neutrophils during early wound healing, with mRNA and protein levels peaking at 2 days post-injury [Murase et al. DOI:10.1007/s00414-017-1658-7].
