Calcium flux through ER-TGN contact sites facilitates cargo export

B. R. Ramazanov, R. Di Martino, A. Kumar, A. Parchure, Y. Kim, O. Griesbeck, M. A. Schwartz, A. Luini, J. von Blume

The paper shows that Ca2+ flux through ER-TGN contact sites is essential for cargo export via SPCA1 and Cab45, using a FRET sensor to measure real-time Ca2+ flow.

Liquid-liquid phase separation facilitates the biogenesis of secretory storage granules

A. PARCHURE, M. Tian, C. K. Boyer, S. C. Bearrows, K. E. Rohli, J. Zhang, B. R. Ramazanov, Y. Wang, S. Stephens, J. von Blume

The paper shows that chromogranin proteins undergo liquid-liquid phase separation at the TGN to recruit and sort proinsulin and other cargo molecules into secretory granules, independent of specific sequence elements.
