Surfactant Pulmonary-Associated Protein D (SP-D) is a 43 kDa member of the collectin family of innate immune modulators. Its principal components consist of a collagen-like region and a C-terminal carbohydrate recognition domain (CRD), a structure that places it in a subset of pattern recognition proteins termed defense collagens. SP-D is constitutively secreted by alveolar lining cells and epithelium associated with tubular structures and induced in cardiac smooth muscle and endothelial cells. It binds both secreted and transmembrane proteins that transduce its function. It binds human neutrophil defensins, modulating influenza anti-viral defense. It binds MD-2/LY96, a secreted protein that cooperates with Toll-like receptors (TLRs) in the response of macrophages to bacterial lipopolysaccharides (LPS) or cell wall components. It also binds macrophage CD14 and TLRs directly, blocking binding of LPS and down-regulating TNF-α secretion. SP-D binding of both SIRPα and the calreticulin/CD91 complex on macrophages allows for a graded response to environmental challenge.

Pulmonary surfactant-associated proteins promote alveolar stability by lowering the surface tension at the air-liquid interface in the peripheral air spaces. SP-B increases the collapse pressure of palmitic acid to nearly 70 millinewtons per meter. SFTPB Protein, Human, Recombinant is expressed in yeast. The predicted molecular weight is 8.7 kDa and the accession number is P07988.

SFTPC Protein, Human, Recombinant (GST) is expressed in E. coli.

In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air-liquid interface in the alveoli of the mammalian lung and is essential for normal respiration. Enhances the expression of MYO18A/SP-R210 on alveolar macrophages.; (Microbial infection) Recognition of M.tuberculosis by dendritic cells may occur partially via this molecule. Can recognize, bind, and opsonize pathogens to enhance their elimination by alveolar macrophages. SFTPA1 Protein, Human, Recombinant (B2M & His & Myc) is expressed in E. coli expression system with N-10xHis-B2M and C-Myc tag. The predicted molecular weight is 41.2 kDa and the accession number is Q8IWL2.

Deleted in malignant brain tumors 1 protein, also known as glycoprotein 34, surfactant pulmonary-associated D-binding protein, DMBT1 and GP34, is a secreted protein which belongs to theDMBT1 family. DMBT1 contains 2CUB domains, 14SRCR domains and 1ZP domain. It is highly expressed in alveolar and macrophage tissues. In some macrophages, expression is detected on the membrane, and in other macrophages, it is strongly expressed in the phagosome/phagolysosome compartments. Defects in DMBT1 are involved in the development of glioma (GLM). Gliomas are central nervous system neoplasms derived from glial cells and comprise astrocytomas, glioblastoma multiforme, oligodendrogliomas , and ependymomas. DMBT1 may be considered as a candidate tumor suppressor for brain, lung, esophageal, gastric, and colorectal cancers. It may play roles in mucosal defense system, cellular immune defense and epithelial differentiation. DMBT1 may play a role as an opsonin receptor for SFTPD and SPAR in macrophage tissues throughout the body, including epithelial cells lining the gastrointestinal tract. It may be an important factor in fate decision and differentiation of transit-amplifying ductular (oval) cells within the hepatic lineage. DMBT1 may function as a binding protein in saliva for the regulation of taste sensation. It binds to HIV-1 envelope protein and has been shown to both inhibit and facilitate viral transmission.

Pulmonary surfactant-associated protein B, also known as SFTPB and SP-B, contains one saposin A-type domain and three saposin B-type domains. SP-B is produced primarily by alveolar type II cells (AEC2) but also by nonciliated respiratory epithelial cells lining distal portions of the respiratory tract. Its secretion promotes alveolar homeostasis, stabilizing lipid layers and lowering surface tension at the air-liquid interface in the peripheral air spaces. Alveolar SP-B influences surfactant formation, effector cell functions, and innate host defense. Deficiency is associated with respiratory distress syndrome (RDS), pulmonary surfactant metabolism dysfunction 1 (SMDP1), and other human lung diseases. Gene addition and editing therapies show promise by complementing SP-B expression in AEC2s, restoring the phenotypic defect in vitro and in vivo.
