Sftpb Gene Summary [Mouse]
Predicted to be involved in respiratory gaseous exchange by respiratory system and sphingolipid metabolic process. Located in cytoplasm. Is expressed in lung surfactant and respiratory system. Human ortholog(s) of this gene implicated in lung disease (multiple); respiratory syncytial virus infectious disease; and toxic shock syndrome. Orthologous to human SFTPB (surfactant protein B).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Sftpb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

- Saposin-like type B, region 1
- Saposin-like type B, region 2
