We have studied the effects of ITIM-bearing FcgammaRIIB2 on the FcepsilonRI-dependent nuclear shuttling of mitogen-activated protein (MAP) kinase (ERK2) in rat basophilic leukemia (RBL-2H3) cells. The cross-linking of FcepsilonRI elicited the sustained increase of the intracellular calcium ion concentration ([Ca(2+)](i)) and the translocation of ERK2 from the cytoplasm to the nucleus. The import of ERK2 to the nucleus reached the maximum at 6-7 min, thereafter ERK2 was exported within 30 min. The co-clustering of FcepsilonRI and FcgammaRIIB2 increased the [Ca(2+)](i) and induced the import of ERK2. However, the calcium increase was transient and ERK2 was rapidly exported to the cytoplasm. In addition, the phosphorylation of ERK2 and the production of TNF-alpha were decreased in case of co-clustering of FcepsilonRI and FcgammaRIIB2. This suggested that the co-clustering negatively control the production of pro-inflammatory cytokines through the suppression of nuclear shuttling of ERK2.
