Protein Structure

UniProt Annotation

Function

Bactericidal C-type lectin which acts exclusively against Gram-positive bacteria and mediates bacterial killing by binding to surface-exposed carbohydrate moieties of peptidoglycan. Restricts bacterial colonization of the intestinal epithelial surface and consequently limits activation of adaptive immune responses by the microbiota. The uncleaved form has bacteriostatic activity, whereas the cleaved form has bactericidal activity against L.monocytogenes and methicillin-resistant S.aureus. Regulates keratinocyte proliferation and differentiation after skin injury. {ECO:0000269PubMed:19095652}.

Subcellular Localization

Secreted. Cytoplasm {ECO:0000250}.

Disease Associations

Tissue Specificity

Predominantly expressed in pancreas, where it may be restricted to exocrine pancreas. Moderate expression levels in testis and weak in heart, kidney and placenta. {ECO:0000269PubMed:15556304, ECO:0000269PubMed:15777617}.
