SMAD2 Antibody

SMAD2: ubiquitously expressed transcription factor phosphorylated and activated by TGF-beta receptor-type kinases. Participates in a wide range of critical processes including morphogenesis, cell-fate determination, proliferation, differentiation and apoptosis. Phosphorylated Smads dimerize with collaborating Smad4 and are translocated into the nucleus, where the transcription of target genes is stimulated. Two alternatively spliced isoforms have been described.
