Deskripsi
STIM proteins sense Ca2+ depletion in the ER and activate store-operated Ca2+ entry in response, a process associated with dendritic cell (DC) functions. Here, the authors show that optimal antigen cross-presentation in DCs requires the association of the chaperone molecule UNC93B1 with STIM1.
