Recombinant Human SMAD2 (C-terminal SXS deletion) fused with GST tag at N-terminal was expressed in E. coli.
SMADs are essential intracellular components for the signal transduction of TGFbeta family members. SMAD2 is an intracellular mediator of TGFbeta family and activin type 1 receptor. SMAD2 mediate TGFbeta signaling to regulate cell growth and differentiation. SMAD2 is released from cytoplasmic retention by TGFbeta receptor-mediated phosphorylation. The phosphorylated SMAD2 then forms a heterodimeric complex with SMAD4, and this complex translocates from cytoplasm into nucleus. By interacting with DNA-binding proteins, SMAD2 complexes then positively or negatively regulate the transcription of target genes. Inactivating mutations in SMAD2 have been found in various cancers.
