Tmem38b Gene Summary [Mouse]
Predicted to enable potassium channel activity. Acts upstream of or within several processes, including cellular response to caffeine; lung development; and regulation of cardiac muscle contraction by regulation of the release of sequestered calcium ion. Located in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 14. Orthologous to human TMEM38B (transmembrane protein 38B).

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 Tmem38b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
