Glycoprotein-340 is member of the scavenger receptor superfamily and has been identified as a putative SP-D receptor. Gp-340 has been shown to bind SP-D in a calcium dependent manner through a protein-protein interaction. Like SP-D, gp-340 is mainly found in lung tissue and immunohistochemistry revealed high expression in alveolar macrophages (3). An identical protein is present in saliva (salivary agglutinin) and both forms are encoded by the gene DMBT1 (6).
Native gp-340 purified from bronchioaveolar lavage from proteinosis patients
HYB 213-06 is specific for gp-340
Not determined
In Western blotting after SDS-PAGE HYB 213-06 reacts strongly with gp-340 in non-reduced forms.
