Summaries for JPH3 Gene

Entrez Gene Summary for JPH3 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. 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]

GeneCards Summary for JPH3 Gene

JPH3 (Junctophilin 3) is a Protein Coding gene. Diseases associated with JPH3 include Huntington Disease-Like 2 and Huntington Disease. GO annotations related to this gene include calcium-release channel activity. An important paralog of this gene is JPH2.

UniProtKB/Swiss-Prot for JPH3 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. JPH3 is brain-specific and appears to have an active role in certain neurons involved in motor coordination and memory.

  • Huntington disease-like 2 (HDL2) [MIM:606438]: Huntington disease (HD) is a neurodegenerative disorder resulting primarily from the loss of medium spiny projection neurons in the striatum, especially in the caudate nucleus, and, to a lesser extent, atrophy of mesencephalic and cortical structures. The typical clinical picture of HD combines familial adult onset chorea and subcortical dementia that usually begin during the fourth decade of life. {ECO:0000269 PubMed:11914418, ECO:0000269 PubMed:14557581}.
