  • FunctionCalcium-dependent lectin involved in innate immune defense. Binds mannose, fucose and N-acetylglucosamine on different microorganisms and activates the lectin complement pathway. Binds to late apoptotic cells, as well as to apoptotic blebs and to necrotic cells, but not to early apoptotic cells, facilitating their uptake by macrophages. May bind DNA.
  • Tissue specificityPlasma protein produced mainly in the liver.
  • Involvement in diseaseNote=There is an association between low levels of MBL2 and a defect of opsonization which results in susceptibility to frequent and chronic infections.
  • Sequence similaritiesContains 1 C-type lectin domain.
    Contains 1 collagen-like domain.
  • Cellular localizationSecreted.
