Biochemical and Physiological Mechanisms
SMAD2(Mothers against decapentaplegic homolog 2) belongs to the SMAD family of proteins that mediate signal transduction by the TGF-beta/activin/BMP-2/4 cytokine superfamily from receptor Ser/Thr protein kinases at the cell surface to the nucleus. Phospho

Recombinant Human SMAD2 Protein (rp220384) - SDS-PAGE 3 μg/lane of Recombinant Human SMAD2 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 43.3 kDa under reducing conditions and 38.4 & 41.8 & 82.4 & 126.2 kDa under non-reducing conditions. The conserved cysteine residues (Cys267, Cys330) on the surface of SMAD2 participate in disulfide bond formation. Under non-reducing conditions, these disulfide bonds remain intact, leading to distinct spatial conformations of the protein. Oligomerization is a critical step in SMAD2-mediated signal transduction (PMID: 10615055).
