      DescriptionAnti-phospho-Smad1 (Ser463/465) Antibody
      Background InformationSmad proteins, the mammalian homologs of the Drosophila Mothers against dpp (Mad), function downstream of TGF-β receptor Serine/Threonine kinases and undergo serine phosphorylation in response to receptor activation. Following BMP (bone morphogenic protein) or TGF-β binding to the targeted surface receptors, Smad1 (also designated Madr1 or JV4-1) becomes phosphorylated at Ser 463 and Ser 465. Activated Smad1 associates with Smad4 and translocates to the nucleus, where the Smad1/Smad4 complex recruits DNA-binding proteins to activate specific gene transcription. BMP binding induces phosphorylation of Smad1, which enhances the binding of Smad1 to CBP to stimulate Smad1-dependent transcription. In addition, ALK1 and ALK2 specifically phosphorylate Smad1 on residues located in the MH2 domain and induces Smad1-dependent pathways.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene belongs to the SMAD, a family of proteins similar to the gene products of the Drosophila gene 'mothers against decapentaplegic' (Mad) and the C. elegans gene Sma. SMAD proteins are signal transducers and transcriptional modulators that mediate multiple signaling pathways. This protein mediates the signals of the bone morphogenetic proteins (BMPs), which are involved in a range of biological activities including cell growth, apoptosis, morphogenesis, development and immune responses. In response to BMP ligands, this protein can be phosphorylated and activated by the BMP receptor kinase. The phosphorylated form of this protein forms a complex with SMAD4, which is important for its function in the transcription regulation. This protein is a target for SMAD-specific E3 ubiquitin ligases, such as SMURF1 and SMURF2, and undergoes ubiquitination and proteasome-mediated degradation. Alternatively spliced transcript variants encoding the same protein have been observed.
