Definition Homo sapiens junctophilin 2 (JPH2), transcript variant 2, mRNA.
Product junctophilin-2 isoform 2

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].

Transcript Variant: This variant (2) uses an alternate 3' terminal exon, compared to variant 1, resulting in a shorter isoform (2), compared to isoform 1.
