Supplementary information

The Signal Transducer and Activator of Transcription 4 (STAT4) is a critical member of the STAT protein family. It weighs approximately 85 kDa. STAT4 primarily functions as a transcription factor activated by phosphorylation through Janus kinases (JAKs) in response to cytokine signaling. This protein facilitates the translocation into the nucleus where it promotes the transcription of specific genes. STAT4 expression occurs mainly in T cells and natural killer (NK) cells indicating its role in the immune response.
Biological function summary

STAT4 is integral to the differentiation of naïve T cells into T helper 1 (Th1) cells. These Th1 cells play a central role in orchestrating immune responses against intracellular pathogens. STAT4 activation requires two distinct steps involving JAK kinases and subsequent binding to DNA regulatory elements of target genes. STAT4 does not function as part of a large protein complex but rather operates as a dimer following phosphorylation.

Pathways

STAT4 participates strongly in the JAK-STAT signaling pathway fundamental for immune cell maturation and response. The JAK-STAT pathway regulates several biological processes including proliferation and inflammation. STAT4 works closely with STAT1 in promoting Th1 differentiation while also interacting with other proteins like IL-12 to modulate immune activity. These interactions emphasize its influence in immune responses and could affect inflammatory pathways.

STAT4 exhibits associations with autoimmune diseases such as rheumatoid arthritis and systemic lupus erythematosus. Aberrant STAT4 activity can lead to dysregulated immune responses making it a significant target in these disorders. In the context of rheumatoid arthritis altered STAT4 signaling enhances inflammation through its connection with other immune proteins like IL-23. Understanding STAT4's role in these diseases may offer avenues for therapeutic interventions and better management of immune-related conditions.

Target data

Transcriptional regulator mainly expressed in hematopoietic cells that plays a critical role in cellular growth, differentiation and immune response (PubMed : 10961885, PubMed : 37256972, PubMed : 8943379). Plays a key role in the differentiation of T-helper 1 cells and the production of interferon-gamma (PubMed : 12213961, PubMed : 35614130). Also participates in multiple neutrophil functions including chemotaxis and production of the neutrophil extracellular traps (By similarity). After IL12 binding to its receptor IL12RB2, STAT4 interacts with the intracellular domain of IL12RB2 and becomes tyrosine phosphorylated (PubMed : 10415122, PubMed : 7638186). Phosphorylated STAT4 then homodimerizes and migrates to the nucleus where it can recognize STAT target sequences present in IL12 responsive genes. Although IL12 appears to be the predominant activating signal, STAT4 can also be phosphorylated and activated in response to IFN-gamma stimulation via JAK1 and TYK2 and in response to different interleukins including IL23, IL2 and IL35 (PubMed : 11114383, PubMed : 34508746). Transcription activation of IFN-gamma gene is mediated by interaction with JUN that forms a complex that efficiently interacts with the AP-1-related sequence of the IFN-gamma promoter (By similarity). In response to IFN-alpha/beta signaling, acts as a transcriptional repressor and suppresses IL5 and IL13 mRNA expression during response to T-cell receptor (TCR) activation (PubMed : 26990433).
