Abstract

Differentiation of naive CD4 T cells into Th2 cells requires protein expression of GATA3. Interleukin-4 induces STAT6 activation and subsequent GATA3 transcription. Little is known, however, on how T cell receptor-mediated signaling regulates GATA3 and Th2 cell differentiation. Here we demonstrated that T cell receptor-mediated activation of the Ras-ERK MAPK cascade stabilizes GATA3 protein in developing Th2 cells through the inhibition of the ubiquitin-proteasome pathway. Mdm2 was associated with GATA3 and induced ubiquitination on GATA3, suggesting its role as a ubiquitin-protein isopeptide ligase for GATA3 ubiquitination. Thus, the Ras-ERK MAPK cascade controls GATA3 protein stability by a post-transcriptional mechanism and facilitates GATA3-mediated chromatin remodeling at Th2 cytokine gene loci leading to successful Th2 cell differentiation.
