Rhomboid protease RHBDL2 is a calcium-activated suppressor of EGFR signalling in keratinocytes.

Nicholas Johnson, Jan Dohnálek, Jana Březinová, Josef Čáslavský, Aneta Škarková, Njainday Pulo Jobe, Monika Fliegl, Květa Trávníčková, Emma Burbridge, Vahap Canbay, Chatpakorn Rassemeena Christiansen, Ulrich auf dem Keller, Juraj Lábaj, Olha Fedosieieva, Jan Prochazka, , Kvido Střı́šovský

This study identifies RHBDL2 as a calcium-activated rhomboid protease that suppresses EGFR signaling in keratinocytes by shedding its ectodomain, thereby limiting cell migration and invasion.

FAM83H regulates postnatal T cell development through thymic stroma organization

Betul Melike Ogan, Veronika Forstlova, Laura Jane Dowling, Michaela Šímová, Kristína Vičíková, Vendula Novosadová, František Špoutil, Sylvie Cervenkova, Michaela Procházková, Jolana Turečková, Olha Fedosieieva, Juraj Lábaj, Petr Nickl, Kamila Křížová, Jan Procházka, , Jana Balounová

This study shows that FAM83H is essential for thymic stroma organization and T cell development, as its deficiency leads to impaired thymic architecture and reduced T cell production.
