IHC-Fr 1/100.
WB Use at an assay dependent dilution. Predicted molecular weight: 38 kDa.


  • Function
    Contributes to the lung's defense against inhaled microorganisms. May participate in the extracellular reorganization or turnover of pulmonary surfactant. Binds strongly maltose residues and to a lesser extent other alpha-glucosyl moieties.
  • Sequence similarities
    Belongs to the SFTPD family.
    Contains 1 C-type lectin domain.
    Contains 1 collagen-like domain.
  • Post-translational
    The N-terminus is blocked.
    Hydroxylation on proline residues within the sequence motif, GXPG, is most likely to be 4-hydroxy as this fits the requirement for 4-hydroxylation in vertebrates.
  • Cellular localization
    Secreted > extracellular space > extracellular matrix. Secreted > extracellular space > surface film.
