Description
Recombinant full-length human SMAD9 was expressed by baculovirus in E.coli cells using an N-terminal GST tag.
Scientific Background: SMAD9 or SMAD family member 9 is a member of the SMAD family. SMAD9 transduces signals from TGF-beta family members which regulate growth, differentiation, apoptosis, and development. SMAD9 is activated by bone morphogenetic proteins and it interacts with SMAD4 (1). SMAD9 positively and negatively regulate BMP signaling, respectively. SMAD9, also known as SMAD8 may play a role in both pulmonary hypertension and lung tumorigenesis (2). Mutations in SMAD9 in patient with pulmonary arterial hypertension (PAH) have been identified and this may be involved in the pathogenesis of PAH
