JPH2 - junctophilin 2 Gene
Also Known as JP2; JP-2; CMD2E; CMH17
Species: Homo sapiens
About JPH2
This gene has 2 transcripts (splice variants), 218 orthologues, 3 paralogues and is associated with 3 phenotypes. Biased expression in heart (RPKM 14.9), prostate (RPKM 9.1) and 11 other tissues.
Summary
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]
