FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Junctional complexes between the plasma membrane and endoplasmic/sarcoplasmic reticulum are a common feature of all excitable cell types and mediate cross talk between cell surface and intracellular ion channels. The protein encoded by this gene is a component of junctional complexes and is composed of a C-terminal hydrophobic segment spanning the endoplasmic/sarcoplasmic reticulum membrane and a remaining cytoplasmic domain that shows specific affinity for the plasma membrane. This gene is a member of the junctophilin gene family. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a targeted null mutation fail to suckle and die shortly after birth. Mutants exhibit deficiencies of triad junctions and contraction in skeletal muscle. [provided by MGI curators]
