Function

Junctophilin-2. Membrane-binding protein that provides a structural bridge between the plasma membrane and the sarcoplasmic reticulum and is required for normal excitation-contraction coupling in cardiomyocytes (PubMed:20095964). Provides a structural foundation for functional cross-talk between the cell surface and intracellular Ca(2+) release channels by maintaining the 12-15 nm gap between the sarcolemma and the sarcoplasmic reticulum membranes in the cardiac dyads (By similarity). Necessary for proper intracellular Ca(2+) signaling in cardiac myocytes via its involvement in ryanodine receptor-mediated calcium ion release (By similarity). Contributes to the construction of skeletal muscle triad junctions (By similarity). Junctophilin-2 N-terminal fragment. Transcription repressor required to safeguard against the deleterious effects of cardiac stress. Generated following cleavage of the Junctophilin-2 chain by calpain in response to cardiac stress in cardiomyocytes. Following cleavage and release from the membrane, translocates to the nucleus, binds DNA and represses expression of genes implicated in cell growth and differentiation, hypertrophy, inflammation and fibrosis. Modifies the transcription profile and thereby attenuates pathological remodeling in response to cardiac stress. Probably acts by competing with MEF2 transcription factors and TATA-binding proteins.

Activity summary

Junctophilin 2 (JP-2) is a protein that plays an important role in the formation of junctional membrane complexes. It belongs to the junctophilin family and has a mass of approximately 65 kDa. JP-2 is expressed in cardiac and skeletal muscle tissues where it facilitates close connections between the plasma membrane and the sarcoplasmic reticulum. These connections are essential for efficient calcium signaling which is integral to muscle contraction and function.

Biological function summary

JP-2 contributes to the structural bridge between transverse tubules (T-tubules) and the sarcoplasmic reticulum. It is a critical component of the excitation-contraction coupling machinery in muscle cells. JP-2 works as part of a larger protein complex that includes ryanodine receptors and dihydropyridine receptors. These complexes ensure precise delivery and regulation of calcium ions critical to muscle cell contraction.

Pathways

Junctophilin 2 is closely linked within the calcium signaling and muscle contraction pathways. It partners with proteins like the ryanodine receptor (RyR) and the L-type calcium channel both of which are indispensable for calcium ion movement across the muscle cell membranes. JP-2's interaction with these pathways highlights its role in maintaining calcium homeostasis required for muscle function.

Associated diseases and disorders

Junctophilin 2 contributes to conditions such as hypertrophic cardiomyopathy and heart failure. Mutations or dysregulation of JP-2 can disrupt normal calcium signaling and lead to these heart disorders. In the context of hypertrophic cardiomyopathy its disruption affects proteins like the ryanodine receptor indicating its pivotal place in both disease development and potential therapeutic targeting.
