Signal transducer and activator of transcription 6 fragment, (C54H81N13O15), a peptide with the sequence H2N-Ser-Tyr-Trp-Ser-Asp-Arg-Leu-Ile-Ile-OH, MW= 1152.3. STAT6 is a member of the STAT family of transcription factors(1). 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(2). This protein plays a central role in exerting IL4 mediated biological responses(3). 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.
