Function

Carbohydrate-binding lectin with a preference for chitin. Has no chitinase activity. May play a role in tissue remodeling and in the capacity of cells to respond to and cope with changes in their environment. Plays a role in T-helper cell type 2 (Th2) inflammatory response and IL-13-induced inflammation, regulating allergen sensitization, inflammatory cell apoptosis, dendritic cell accumulation and M2 macrophage differentiation. Facilitates invasion of pathogenic enteric bacteria into colonic mucosa and lymphoid organs. Mediates activation of AKT1 signaling pathway and subsequent IL8 production in colonic epithelial cells. Regulates antibacterial responses in lung by contributing to macrophage bacterial killing, controlling bacterial dissemination and augmenting host tolerance. Also regulates hyperoxia-induced injury, inflammation and epithelial apoptosis in lung.

Notes

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

Activity summary

YKL-40 also known as chitinase-3-like protein 1 (CHI3L1) is a glycoprotein with a molecular weight of approximately 40 kDa. Scientists often study it for its roles in inflammatory processes. It has expressions in numerous tissues including liver cartilage and the central nervous system. The CHI3L1 protein does not possess chitinase activity unlike other members of the chitinase family yet it interacts with various ligands to influence cellular behavior.

Biological function summary

YKL-40 plays significant roles in tissue remodeling and inflammation. It does not form part of a larger complex by itself but influences several cellular processes. This protein affects cell proliferation migration and survival making it involved in both normal physiological processes and pathological conditions. CHI3L1 also exhibits a connection to the immune response where it modulates macrophage activity and interacts with other immune cells.

Pathways

YKL-40 is integral to the inflammatory and extracellular matrix pathways. It associates with proteins such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) influencing signaling cascades that modulate inflammation. Through these interactions CHI3L1 becomes a mediator of connective tissue metabolism and immune reactions in various pathophysiological states.

Associated diseases and disorders

YKL-40 shows strong links to conditions like osteoarthritis and certain cancers. In osteoarthritis elevated levels of CHI3L1 reflect increased cartilage degradation while in oncology it correlates with tumor angiogenesis and metastasis potential. Its connection with proteins such as matrix metalloproteinases highlights its role in disease mechanisms highlighting its potential as a biomarker for early detection and disease progression monitoring.
