遺伝子(ID):
タンパク質の説明:
This gene encodes a lung surfactant protein that is a member of a subfamily of C-type lectins called collectins. The encoded protein binds specific carbohydrate moieties found on lipids and on the surface of microorganisms. This protein plays an essential role in surfactant homeostasis and in the defense against respiratory pathogens. Mutations in this gene are associated with idiopathic pulmonary fibrosis. Alternate splicing results in multiple transcript variants.

研究背景

機能:

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 (By similarity).

(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.

PTMs:

N-acetylated.

サブユニット構造:

Oligomeric complex of 6 set of homotrimers.

(Microbial infection) Binds M.bovis cell surface protein Apa via its glycosylated sites; probably also recognizes other bacterial moieties.

(Microbial infection) Binds to the S.aureus extracellular adherence protein, Eap, thereby enhancing phagocytosis and killing of S.aureus by alveolar macrophages.

タンパク質ファミリー:

Belongs to the SFTPA family.

Application: WB    Species: Human    Sample: A549 cell

Figure 4 miR-296-5p inhibited the expression of SP-A (SFTPA1) and SP-B through the Wnt signaling pathway. After transfection of mir-296-5p overexpression and empty vectors in the A549 cell line, the expression of WNT7B, β-catenin, SP-A, and SP-B was assessed using western blotting.
