Protein Array containing more than 19,000 full-length human proteins using ab268115.

Z- and S- Score : The Z-score represents the strength of a signal that a monoclonal antibody (Monoclonal Antibody) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a Monoclonal Antibody to its intended target. A Monoclonal Antibody is considered to specific to its intended target, if the Monoclonal Antibody has an S-score of at least 2.5. For example, if a Monoclonal Antibody binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that Monoclonal Antibody to protein X is equal to 29.

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.
