General description

JPH1 (junctophilin 1) is a subtype of the junctional membrane complex protein called JP, which contains three subtypes. This subtype is predominantly expressed in skeletal muscles. It is expressed in the junctional membrane complexes of excitable cells, and exists as a transmembrane protein. This gene is localized to human chromosome 8q21.1.

Biochem/physiol Actions

Junctophilins span the membrane of intracellular Ca2+ storage vesicles and aids in their interaction with cell-surface membrane, thus, facilitating the formation of junctional membrane complexes. Studies in mice show that this protein plays a crucial role in the formation of triads during skeletal muscle development. JPH1 and GADP-1 are parts of a common pathway, and hence, interdependent. Thus, mutations in GDAP-1 (ganglioside-induced differentiation-associated protein 1) might phenotypically be manifested by JPH1. Therefore, JPH1 is implicated in Charcot-Marie-Tooth (CMT) disease.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
