    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. CAG/CTG repeat expansions at the Huntington's disease (HD)-like 2 locus have been identified in this gene, which is a member of the junctophilin gene family. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Oct 2012]

    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.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (2) lacks several exons and includes an alternate 3' terminal exon compared to variant 1. The latter results in a frame-shift and a much shorter isoform (2) with a distinct C-terminus containing a 13 aa polyalanine stretch compared to isoform 1. This variant is described in PMID:11694876.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (4) contains an alternate 5' terminal exon and is alternately spliced at the 3' end compared to variant 1. The latter renders this variant a candidate for nonsense-mediated mRNA decay (NMD), hence it is represented as non-coding.
