  • Function

    Lectin that functions as pattern receptor specific for beta-1,3-linked and beta-1,6-linked glucans, such as cell wall constituents from pathogenic bacteria and fungi. Necessary for the TLR2-mediated inflammatory response and for TLR2-mediated activation of NF-kappa-B. Enhances cytokine production in macrophages and dendritic cells. Mediates production of reactive oxygen species in the cell. Mediates phagocytosis of C.albicans conidia. Binds T-cells in a way that does not involve their surface glycans and plays a role in T-cell activation. Stimulates T-cell proliferation.
  • Tissue specificity

    Highly expressed in peripheral blood leukocytes and dendritic cells. Detected in spleen, bone marrow, lung, muscle, stomach and placenta.
  • Involvement in disease

    Defects in CLEC7A may be a cause of familial candidiasis type 4 (CANDF4) [MIM:613108]. It is a rare disorder with altered immune responses and impaired clearance of fungal infections, selective against Candida. It is characterized by persistent and/or recurrent infections of the skin, nails and mucous membranes caused by organisms of the genus Candida, mainly Candida albicans.
  • Sequence similarities

    Contains 1 C-type lectin domain.
  • Post-translational

    Phosphorylated on tyrosine residues in response to glucan binding.
  • Cellular localization

    Cytoplasm and Cell membrane.

Customer reviews and Q&As


Thank you for your enquiry.

As discussed on the telephone, I can confirm that is covered by the guarantee for IHC-P. All tested applications and species covered by the guarantee are listed on the individual datasheets. Further information regarding the guarantee can be found on the following page from the website:


The laboratory have provided the requested IHC protocol. The citrate buffer for antigen retrieval is pH 5.5 and the antibody was used at 5ug/mL. Please note this is a guideline only and may require some individual optimization.

I hope this will be helpful. If you have any further questions, please do not hesitate to contact me.
