SMAD Family Member 9 (SMAD9) Antibody – Rabbit Polyclonal

The protein encoded by this gene is a member of the SMAD family, which transduces signals from TGF-beta family members. The encoded protein is activated by bone morphogenetic proteins and interacts with SMAD4. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]

Smad8: transcription factor phosphorylated and activated by bone morphogenetic protein receptor kinases. Phosphorylated Smads dimerize with collaborating Smad4 and are translocated into the nucleus, where they regulate transcription of target genes. Participates in a wide range of critical processes including morphogenesis, cell-fate determination, proliferation, differentiation and apoptosis. Two alternatively spliced products have been described.
