STAT1 Antibody – Rabbit Polyclonal

STAT1: transcription factor of the STAT family. Phosphorylated and activated by receptor-associated kinases downstream of certain receptor tyrosine kinases, GPCRs, and receptors for various interleukins and interferons. Forms homo- or heterodimers that translocate into the nucleus where they regulate transcription. Two alternatively spliced isoforms have been described.

Protein type: Transcription factor; DNA-binding

Cellular Component: nucleoplasm; axon; nuclear chromatin; cytoplasm; dendrite; nucleolus; nucleus

Molecular Function: identical protein binding; signal transducer activity; protein binding; enzyme binding; protein homodimerization activity; DNA binding; protein phosphatase 2A binding; sequence-specific DNA binding; double-stranded DNA binding; tumor necrosis factor receptor binding; transcription factor activity; CCR5 chemokine receptor binding

Biological Process: transcription from RNA polymerase II promoter; response to peptide hormone stimulus; response to cAMP; blood circulation; positive regulation of transcription, DNA-dependent; positive regulation of smooth muscle cell proliferation; response to lipopolysaccharide; signal transduction; response to exogenous dsRNA; tumor necrosis factor-mediated signaling pathway; regulation of transcription, DNA-dependent; positive regulation of cell proliferation; negative regulation of viral protein levels in host cell; lipopolysaccharide-mediated signaling pathway; response to nutrient; caspase activation; response to drug; transcription, DNA-dependent; cytokine and chemokine mediated signaling pathway; negative regulation of I-kappaB kinase/NF-kappaB cascade; JAK-STAT cascade; negative regulation of angiogenesis; cellular response to insulin stimulus; response to bacterium; response to mechanical stimulus; response to cytokine stimulus; negative regulation of endothelial cell proliferation; positive regulation of transcription from RNA polymerase II promoter
