- Triadin/Junctin double null mouse reveals a differential role for Triadin and Junctin in anchoring CASQ to the jSR and regulating Ca(2+) homeostasisSimona Boncompagni
DNI Department of Neuroscience and Imaging, CeSI Center for Research on Ageing, University of G d Annunzio, Chieti, Italy
PLoS ONE 7:e39962. 2012..These data suggest that in skeletal muscle the disruption of Tdn/CASQ link has a more profound effect on jSR architecture and myoplasmic Ca(2+) regulation than Jct/CASQ association...

Age (Dordr) 34:27-41. 2012..We conclude that TAs do not arise abruptly but are the final result of a gradually changing SR architecture and we suggest that the crystalline ATPase within the aggregates may be inactive...

J Gerontol A Biol Sci Med Sci 61:995-1008. 2006..These data indicate that in aging humans the EC coupling apparatus undergoes a partial disarrangement and a spatial reorganization that could interfere with an efficient delivery of Ca(2+) ions to the contractile proteins...
- Structural differentiation of skeletal muscle fibers in the absence of innervation in humansSimona Boncompagni
