[[http://www.uniprot.org/uniprot/SMAD1_HUMAN SMAD1_HUMAN]] Defects in SMAD1 may be a cause of primary pulmonary hypertension (PPH1) [MIM:[http://omim.org/entry/178600 178600]]. 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 PPH1 is rare, cases secondary to known etiologies are more common and include those associated with the appetite-suppressant drugs.<ref>PMID:21898662</ref> | |||

[[http://www.uniprot.org/uniprot/SMUF1_HUMAN SMUF1_HUMAN]] E3 ubiquitin-protein ligase that acts as a negative regulator of BMP signaling pathway. Mediates ubiquitination and degradation of SMAD1 and SMAD5, 2 receptor-regulated SMADs specific for the BMP pathway. Promotes ubiquitination and subsequent proteasomal degradation of TRAF family members and RHOA.<ref>PMID:10458166</ref><ref>PMID:19937093</ref><ref>PMID:21402695</ref> [[http://www.uniprot.org/uniprot/SMAD1_HUMAN SMAD1_HUMAN]] Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD1 is a receptor-regulated SMAD (R-SMAD). SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1.<ref>PMID:12097147</ref> | |||
