Biolegend, 648849, Purified anti-STAT4 Antibody, 100μg

Signal Transducer and Activator of Transcription 4 (STAT4) is a critical transcription factor involved in mediating immune responses. STAT4 is primarily activated via phosphorylation which leads to its dimerization, nuclear translocation, and subsequent activation of target genes involved in immune regulation. STAT4 plays a pivotal role in the differentiation of T helper 1 (Th1) cells, follicular helper T cells (Tfh), and regulatory T cells (Tregs), and is essential for the function of natural killer (NK) cells and CD8+ T cells. STAT4 expression is tightly regulated and varies across cell types and activation states, with higher expression observed in activated immune cells such as mature dendritic cells and monocytes. Genetic polymorphisms in the STAT4 gene, such as H623Y and A635V, have been linked to altered STAT4 activity and nuclear localization, influencing susceptibility to various diseases, such as rheumatoid arthritis, systemic lupus erythematosus, type 1 diabetes, and inflammatory bowel disease.
