Biological function summary
This transcription factor is pivotal for manufacturing interferon-gamma (IFN-γ) initiating and sustaining Th1 cell immunity. T-bet doesn't act alone; it functions as part of larger protein complexes interacting with other transcription factors and cofactors to exert its effects. The capacity to influence IFN-γ production makes T-bet a significant player in immune responses helping coordinate responses against intracellular pathogens. Moreover the expression of T-bet is not limited solely to T cells but also impacts other immune cells like CD8+ T cells and B cells. Anti-bet or anti-T antibodies frequently target T-bet in research to explore immune system intricacies better.
Pathways
T-bet integrates into the immune signaling network through pathways such as the JAK-STAT pathway and the Th1 differentiation pathway. It activates transcription of the IFNG gene working closely with related proteins like STAT4. T-bet's influence extends as it cooperates with STAT1 enabling a feed-forward loop that amplifies and stabilizes Th1 responses. "Bet t products" could refer to those derived from such transcriptional activation. Additionally T-bet involvement goes beyond transcriptional regulation affecting cytokine transport and secretion processes vital for an effective immune response.

General info
Function
Lineage-defining transcription factor which initiates Th1 lineage development from naive Th precursor cells both by activating Th1 genetic programs and by repressing the opposing Th2 and Th17 genetic programs (PubMed : 10761931). Activates transcription of a set of genes important for Th1 cell function, including those encoding IFN-gamma and the chemokine receptor CXCR3. Induces permissive chromatin accessibilty and CpG methylation in IFNG (PubMed : 33296702). Activates IFNG and CXCR3 genes in part by recruiting chromatin remodeling complexes including KDM6B, a SMARCA4-containing SWI/SNF-complex, and an H3K4me2-methyltransferase complex to their promoters and all of these complexes serve to establish a more permissive chromatin state conducive with transcriptional activation (By similarity). Can activate Th1 genes also via recruitment of Mediator complex and P-TEFb (composed of CDK9 and CCNT1/cyclin-T1) in the form of the super elongation complex (SEC) to super-enhancers and associated genes in activated Th1 cells (PubMed : 27292648). Inhibits the Th17 cell lineage commitment by blocking RUNX1-mediated transactivation of Th17 cell-specific transcriptinal regulator RORC. Inhibits the Th2 cell lineage commitment by suppressing the production of Th2 cytokines, such as IL-4, IL-5, and IL- 13, via repression of transcriptional regulators GATA3 and NFATC2. Protects Th1 cells from amplifying aberrant type-I IFN response in an IFN-gamma abundant microenvironment by acting as a repressor of type-I IFN transcription factors and type-I IFN-stimulated genes. Acts as a regulator of antiviral B-cell responses; controls chronic viral infection by promoting the antiviral antibody IgG2a isotype switching and via regulation of a broad antiviral gene expression program (By similarity). Required for the correct development of natural killer (NK) and mucosal-associated invariant T (MAIT) cells (PubMed : 33296702).
Post-translational modifications
Phosphorylations at Ser-53, Tyr-77, Ser-225 and Ser-513 are regulated by mTORC1. Phosphorylation at Tyr-530 is essential for its interaction GATA3. Phosphorylation at Tyr-220, Tyr-266 and Tyr-305 enhances its transcriptional activator activity. Phosphorylation at Thr-303 is required for its interaction with NFATC2.. Ubiquitinated at Lys-314, 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-303 (By similarity). Deubiquitinated by USP10 leading to its stabilization (PubMed:24845384).
