Overview
SMAD1 transcription factor phosphorylated and activated by bone morphogenetic protein type 1 receptor kinases. Participates in a wide range of critical processes including morphogenesis, cell-fate determination, proliferation, differentiation and apoptosis. Phosphorylated forms dimerize with collaborating Smad4 and are translocated into the nucleus, where the transcription of target genes is stimulated. Note: This description may include information from UniProtKB.
Protein type: Transcription factor; DNA-binding
Chromosomal Location of Human Ortholog: 4q31
Cellular Component: cytoplasm; cytosol; nuclear inner membrane; nucleoplasm; nucleus; protein complex
Molecular Function: identical protein binding; protein binding; protein kinase binding; transcription factor activity; transforming growth factor beta receptor, pathway-specific cytoplasmic mediator activity
Biological Process: BMP signaling pathway; embryonic pattern specification; positive regulation of transcription from RNA polymerase II promoter; primary microRNA processing; SMAD protein complex assembly
Reference #:  Q15797 (UniProtKB)
