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
modificationsThe 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. - Information by UniProt
