Summary: 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
