Protein name:
Junctophilin-2 (JP-2) ;
Alternative:
Junctophilin type 2 ;
Organism:
Rat (Rattus norvegicus).
General Annotation
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.
Subcellular Location:
Cell membrane
Peripheral membrane protein
Endoplasmic reticulum membrane
Single-pass type IV membrane protein
Sarcoplasmic reticulum membrane
Single-pass type IV membrane protein
Localized predominantly on the plasma membrane. The transmembrane domain is anchored in endoplasmic/sarcoplasmic reticulum membrane, while the N-terminal part associates with the plasma membrane. In heart cells, it predominantly associates along Z lines within myocytes. In skeletal muscle, it is specifically localized at the junction of A and I bands.
