Abstract excerpt
Signal transducer and activator of transcription (STAT) proteins are latent cytoplasmic transcription factors essential for cytokine signaling. Our previous study showed that interleukin-3 (IL-3) induced STAT5 translocation to mitochondria and binding to mitochondrial DNA (mtDNA) in vitro. In this report, we further demonstrated in vivo binding of endogenous STAT5a to mtDNA transcriptional control region and...
