SEQUENCE SIMILARITIES

Belongs to the transcription factor STAT family.

POST-TRANSLATIONAL MODIFICATION

Tyrosine phosphorylated on Tyr-641 following stimulation by IL4/interleukin-4. Tyrosine phosphorylated following stimulation by IL3/interleukin-3 (By similarity). Dephosphorylation on tyrosine residues by PTPN2 negatively regulates the IL4/interleukin-4 mediated signaling.; Mono-ADP-ribosylated by PARP14.

SUBCELLULAR LOCATION

Cytoplasm, nucleus.

FUNCTION

In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein STAT6 plays a central role in exerting IL4 mediated biological responses. It is found to induce the expression of BCL2L1/BCL-X(L), which is responsible for the anti-apoptotic activity of IL4. Knockout studies in mice suggested the roles of this gene in differentiation of T helper 2 (Th2), expression of cell surface markers, and class switch of immunoglobulins.
