SMAD 1/5/8/9 (SMAD5) Antibody – Rabbit Polyclonal

The protein encoded by this gene is involved in the transforming growth factor beta signaling pathway that results in an inhibition of the proliferation of hematopoietic progenitor cells. The encoded protein is activated by bone morphogenetic proteins type 1 receptor kinase, and may be involved in cancer. Alternative splicing results in multiple transcript variants.

SMAD5: 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.
