Total cell lysate (15 µg protein) from non-treated and 100 ng/mL recombinant human IL-4 treated Daudi cells (10 min treatment) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to nitrocellulose, and probed with 1:2500 (0.2 µg/mL) diluted purified anti-STAT6 phospho (Tyr641) antibody (clone A15137E) (upper). Proteins were visualized using 1:3000 diluted HRP goat anti-mouse-IgG secondary antibody (clone Poly4053) and chemiluminescence detection. Direct-Blot™ HRP anti-β-actin Antibody (1:2000 diluted, clone 2F1-1) was used as a loading control (lower). Lane M is the MW ladder.

Description

STAT6 is a member of the signal transducer and activator of transcription (STAT) family, activating gene expression in response to IL-4 and IL-13 stimulation. Upon cytokine stimulation, the receptor is phosphorylated by the associated Janus Kinases (Jak), followed by recruiting cytoplasmic STAT6. The Tyr641 residue of STAT6 is, in turn, phosphorylated by Jak. Phosphorylated STAT6 forms homodimers, translocates to the nucleus, and regulates transcription of target genes. STAT6 plays crucial roles in differentiation of T helper 2 (Th2) cells, class switch of immunoglobulins in B cells, expression of cell surface markers such as MHC class II, and the development of allergic inflammation.

Application

WB - Quality tested
ICFC - Verified

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.1 - 1.0 µg/ml. For intracellular flow cytometric staining, the suggested use of this reagent is ≤0.03 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Human STAT6 has three isoforms; the molecular weights are 94, 82 and 74kD. The immunogen (phosphorylated peptide) is shared by these three isoforms. This antibody recognizes STAT6 Phospho (Tyr641) in all three isoforms. The predominant band detected is at 94 kD.

Clone A15137E does not react with mouse.

This clone is not recommended for ChIP (Chromatin Immunoprecipitation) assays (as determined by in-house testing).

Antigen Details

Structure
847 amino acids with a predicted molecular weight of 94 kD. Contains a SH2 domain responsible for phosphor-Tyrosine binding and dimerization.
Distribution

Cytoplasm; translocates to the nucleus when phosphorylated.

Function
STAT6 is a transcription factor, mediating IL-4 and IL-13 signaling. While STAT6 is widely expressed in human tissues, it exhibits elevated expression in peripheral blood lymphocytes, colon, intestine, ovary, prostate, thymus, spleen, kidney, liver, lung, and placenta. Following phosphorylation by Janus kinases, STAT6 translocates to the nucleus where it regulates gene transcription.
Interaction
STAT6 interacts with CBP/p300 and NCOA1. Forms a homodimer or a heterodimer with other STAT family members.
