STAT1 Antibody

Chen et al.(1998) determined the crystal structure of the DNA complex of a 67-kD core fragment of the Signal Transducer and Activator of Transcription 1 homodimer, lacking only the N-domain and the C-terminal transcriptional activation domain, at 2.9-angstrom resolution. Phosphorylation of STAT1 was also decreased in rheumatoid arthritis lymphocytes. It plays a key role in immunity against mycobacterial and viral infections. Activation of the STAT pathway is important in fibroblast growth factor (FGF) modulation of chondrocyte proliferation and endochondral bone formation during embryogenesis.
