Biolegend, 948604, Alexa Fluor® 488 anti-GATA4 Antibody

GATA binding protein 4 (GATA4) is a zinc-finger transcription factor that plays a crucial role in transcriptional activation and cell growth, differentiation, survival, and senescence. It is essential to cardiac development and function. Along with GATA6, it modulates cardiac stress response and regulates cardiomyocyte formation, replication, and function. GATA4 participates in second heart field transcription and differentiation and ventricular morphogenesis through downstream regulation of Mef2c and Hand2. Mutations in GATA4 can result in myocardial abnormalities, myocardial hypoplasia, absence of a proepicardium, abnormal valve formation, and endocardial cushion defects. In the intestine, GATA4, along with GATA6, is also responsible for regulating epithelial cytodifferentiation and structure, and for maintaining balance between enterocytes and secretory cells through the coordination of Notch signaling. GATA4 plays a vital role in human testicular development through its regulation of the expression of steroidogenic factors StAR, INHA, HSD3B2, and CYP19A1 and sex-determining genes SRY, AMH, and SOX9.
