SMAD1 (human)

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.
