Summaries for JPH2 Gene

Entrez Gene Summary for JPH2 Gene

  • 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. Alternative splicing has been observed at this locus and two variants encoding distinct isoforms are described. [provided by RefSeq, Jul 2008]

GeneCards Summary for JPH2 Gene

JPH2 (Junctophilin 2) is a Protein Coding gene. Diseases associated with JPH2 include cardiomyopathy, familial hypertrophic 17. GO annotations related to this gene include calcium-release channel activity. An important paralog of this gene is JPH3.

UniProtKB/Swiss-Prot for JPH2 Gene

  • Junctophilins contribute to the formation of junctional membrane complexes (JMCs) which link the plasma membrane with the endoplasmic or sarcoplasmic reticulum in excitable cells. Provides a structural foundation for functional cross-talk between the cell surface and intracellular calcium release channels. JPH2 is necessary for proper intracellular Ca(2+) signaling in cardiac myocytes via its involvement in ryanodine receptor-mediated calcium ion release. Contributes to the construction of skeletal muscle triad junctions.

  • Cardiomyopathy, familial hypertrophic 17 (CMH17) [MIM:613873]: A hereditary heart disorder characterized by ventricular hypertrophy, which is usually asymmetric and often involves the interventricular septum. The symptoms include dyspnea, syncope, collapse, palpitations, and chest pain. They can be readily provoked by exercise. The disorder has inter- and intrafamilial variability ranging from benign to malignant forms with high risk of cardiac failure and sudden cardiac death. {ECO:0000269 PubMed:17509612}. Note=The disease is caused by mutations affecting the gene represented in this entry.
