Overlay histogram showing HeLa cells stained with ab199767 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab199767, 1/500 dilution) for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG [EPR25A] Alexa Fluor® 488 (ab199091) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HeLa cells fixed with 4% formaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab at a 1/100 dilution (shown in green) and ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 594), at a 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

Supplementary information

STAT5b also known as Signal Transducer and Activator of Transcription 5B is a 92-kDa protein involved in signaling processes within the cell. Mechanically it functions as a transcription factor and shuttles between the cytoplasm and nucleus modulating gene expression according to extracellular signals. Upon cytokine binding STAT5b undergoes phosphorylation allowing it to form dimers and translocate to the nucleus. It is expressed in many tissues including the liver immune cells and mammary glands reflecting its role in diverse physiological processes.
Biological function summary

STAT5b plays an important role in regulating cell growth differentiation and apoptosis. It often acts as part of the STAT protein family binding to specific DNA sequences to activate transcription. STAT5b particularly influences immune function and hematopoiesis driving proliferation and differentiation of lymphoid and myeloid cells. Its activity affects glucose homeostasis growth hormone signaling and lactation highlighting its importance in various physiological states and developmental processes.

Pathways

STAT5b integrates into the JAK-STAT signaling pathway a critical route for conveying extracellular information to the nucleus. This pathway includes JAK kinases which activate STAT5b by phosphorylation upon cytokine-receptor engagement. STAT5b also participates in the growth hormone pathway interacting with proteins such as Growth Hormone Receptor and other STAT family members like STAT3. Through these interactions STAT5b helps regulate gene expression associated with growth and differentiation in response to hormonal signals.

STAT5b links to several conditions such as growth hormone insensitivity and leukemia. In growth disorders defects in STAT5b can impair normal growth hormone signal transduction often involving interplay with proteins like the Growth Hormone Receptor. In leukemias aberrant activation or expression of STAT5b contributes to uncontrolled cellular proliferation often accompanied by deregulation of the JAK-STAT pathway. Research into STAT5b offers insights into potential therapeutic targets for these and other related conditions.
