Summaries for SMAD9 Gene

Entrez Gene Summary for SMAD9 Gene

  • 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]

GeneCards Summary for SMAD9 Gene

SMAD9 (SMAD Family Member 9) is a Protein Coding gene. Diseases associated with SMAD9 include pulmonary hypertension, primary, 2 and heritable pulmonary arterial hypertension. Among its related pathways are Signaling pathways regulating pluripotency of stem cells and TGF-beta signaling pathway (KEGG). GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and transforming growth factor beta receptor, pathway-specific cytoplasmic mediator activity. An important paralog of this gene is SMAD1.

UniProtKB/Swiss-Prot for SMAD9 Gene

  • Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD9 is a receptor-regulated SMAD (R-SMAD).

  • Pulmonary hypertension, primary, 2 (PPH2) [MIM:615342]: A rare disorder characterized by plexiform lesions of proliferating endothelial cells in pulmonary arterioles. The lesions lead to elevated pulmonary arterial pression, right ventricular failure, and death. The disease can occur from infancy throughout life and it has a mean age at onset of 36 years. Penetrance is reduced. Although familial pulmonary hypertension is rare, cases secondary to known etiologies are more common and include those associated with the appetite-suppressant drugs. {ECO:0000269 PubMed:21898662}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
