BIOCHEM. BIOPHYS. 290:116-126(1991). CC -!- FUNCTION: CONTRIBUTES TO THE LUNG'S DEFENSE AGAINST INHALED CC MICROORGANISMS. BINDS STRONGLY MALTOSE RESIDUES AND TO A LESSER CC EXTENT OTHER ALPHA-GLUCOSYL MOIETIES. IT COULD PARTICIPATE IN THE CC EXTRACELLULAR REORGANIZATION OR TURNOVER OF PULMONARY SURFACTANT. CC -!- SUBUNIT: OLIGOMERIC COMPLEX OF 4 SET OF HOMOTRIMERS. CC -!- SUBCELLULAR LOCATION: EXTRACELLULAR. CC -!- PULMONARY SURFACTANT CONSISTS OF 90% LIPID AND 10% PROTEIN. THERE CC ARE 4 SURFACTANT ASSOCIATED PROTEIN: 2 COLLAGENOUS, CARBOHYDRATE- CC BINDING GLYCOPROTEINS (SP-A AND SP-D) AND 2 SMALL HYDROPHOBIC CC PROTEINS (SP-B AND SP-C). CC -!- SIMILARITY: CONTAINS A COLLAGENOUS DOMAIN. CC -!- SIMILARITY: CONTAINS 1 C-TYPE LECTIN FAMILY DOMAIN.
