Our study on DFCP1 and lysosome membrane repair is live! We uncover a previously unrecognized role for omegasomes in the cellular response to lysosomal membrane damage, revealing another layer of regulation in how damaged lysosomes are repaired. www.nature.com/articles/s41...

DFCP1-containing ER microdomains mediate lysosomal membrane repair - Nature Cell Biology

Radulovic et al. show that phosphatidylinositol 3-phosphate (PI3P), produced by the phosphatidylinositol 3-kinase PIK3C3, is formed on ER domains after lysosome damage. ER domain PI3P helps to recruit...

The ARLA1A-NAC089 module coordinates ER phagy with the unfolded protein response to maintain cellular homeostasis in plants

Yang et al. reveal that the ARLA1A-NAC089 module couples ER phagy with the UPR in plants. This dual regulatory axis fine-tunes cell survival versus death under stress, providing a mechanistic framework for maintaining ER homeostasis and enhancing environmental resilience.

ER exit sites are dynamic ER subdomains that integrate signals, reshape membranes and steer secretion. Twelve groups in the field came together to map their diversity, regulation, unanswered questions and future directions. www.nature.com/articles/s41...

It was a great pleasure to work on this paper. What started as a small meeting in January this year resulted in this beautiful piece of work.
