Deskripsi

STIM proteins sense Ca2+ depletion in the ER and activate store-operated Ca2+-entry (SOCE) in response, a process associated with dendritic cell functions. Here the authors show STIM1 is the major isoform controlling SOCE in mouse dendritic cells and provide a mechanism for its requirement in antigen cross-presentation.
