Phosphorylations at Ser-52, Tyr-76, Ser-224 and Ser-508 are regulated by mTORC1. Phosphorylation at Tyr-525 is essential for its interaction GATA3. Phosphorylation at Tyr-219, Tyr-265 and Tyr-304 enhances its transcriptional activator activity. Phosphorylation at Thr-302 is required for its interaction with NFATC2.; Ubiquitinated at Lys-313, leading to its degradation by the proteasome. Ubiquitination is essential for controlling protein stability, binding to the T-box-binding element of the IFN-gamma promoter, and for interaction with NFATC2 through induction of phosphorylation at Thr-302. Deubiquitinated by USP10 leading to its stabilization (By similarity).
T helper (Th) lymphocytes differentiate into two unique subsets, Th1 and Th2, which differ both in function and in the cytokines they secrete. Th1 and Th2 cytokines promote the growth and differentiation of their subset, and inhibit the growth and differentiation of the opposing subset. T-bet (T box expressed in T cells) is a Th1-specific T box transcription factor that controls the expres-sion of the Th1 cytokine, IFN-γ. T-bet also converts effector Th2 cells into the opposing Th1 subset. T-bet is selectively expressed in Th1 cells. The level of T-bet expression is increased by signals mediated by the T cell receptor (TCR). IL-12 also induces an increase in the level of T-bet. T-bet was originally isolated from nuclear extracts of resting and PMA/ionomycin-activated AE7 cells. T-bet is expressed in low levels in AE7 cells, and in increased levels in stimulated AE7.
