ELISA Use at an assay dependent dilution.


  • Function

    Contributes to the stabilization of the junctional membrane complexes, which are common to excitable cells and mediate cross-talk between cell surface and intracellular ion channels. Probably acts by anchoring the plasma membrane and endoplasmic reticulum. May play an active role in certain neurons involved in motor coordination.
  • Tissue specificity

    Specifically expressed in brain.
  • Involvement in disease

    Defects in JPH3 are the cause of Huntington disease-like type 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.
  • Sequence similarities

    Belongs to the junctophilin family.
    Contains 8 MORN repeats.
  • Domain

    The MORN (membrane occupation and recognition nexus) repeats contribute to the plasma membrane binding, possibly by interacting with phospholipids.
  • Cellular localization

    Cell membrane. Endoplasmic reticulum membrane. Localized predominantly on the plasma membrane. The transmembrane domain is anchored in endoplasmic reticulum membrane, while the N-terminal part associates with the plasma membrane.
