Outline of Final Research Achievements |
Ryanodine receptor is the sarcoplasmic reticulum calcium release channel. We tried to investigate the interaction between ryanodine receptor and its stabilizing factor, FKBP12, by in-cell NMR. However, we did not succeed to deliver the protein of interest to myogenic cells. Thus, I changed the originally planned research project for the study focused on the interaction the protein complex (uncoupling protein 3 (UCP3) and HAX-1) that was involved in the control of the calcium influx into the mitochondria. The NMR and CD experiments showed that calcium-induced folding and stabilization of the C-terminal region of HAX-1 enable it to interact with UCP3. Moreover, the NMR experiment using two different detergents suggested that the C-terminal region could bind to biological membrane.
