Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables identical protein binding activity and potassium channel activity. Acts upstream of or within several processes, including cellular response to caffeine; monoatomic cation transmembrane transport; and regulation of cardiac muscle contraction by regulation of the release of sequestered calcium ion. Located in nuclear membrane and sarcoplasmic reticulum. Is expressed in head mesenchyme; tongue; and vertebral axis musculature. Orthologous to human TMEM38A (transmembrane protein 38A).
