Anti-JPH2

Anti-JPH2 Antibody was affinity purified from monospecific antiserum by immunoaffinity chromatography. Cross reactivity with JPH2 from other sources has not been determined. Protein function: 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. JPH2 is necessary for proper intracellular Ca(2+) signaling in cardiac myocytes via its involvement in ryanodine receptor-mediated calcium ion release. Contributes to the construction of skeletal muscle triad junctions. [The UniProt Consortium]
