Synthetic peptide encompassing the phosphorylated serine 465 and 467 residues of human, mouse and rat Smad2

Smad proteins are intracellular signal transducers and downstream effectors of TGF-beta/BMP signaling. Three distinct classes of Smads have been defined: the receptor-regulated (R-Smads), which include Smad1, 2, 3, 5, 8; the common-mediator Smads (co-Smads), including Smad4, and the antagonistic or inhibitory Smads (I-Smads), including Smad6 and 7 (1).
Smad2 is a ubiquitously expressed, 58kD protein that is phosphorylated and translocates to the nucleus in response to TGF-beta stimulation. After activation of TGF-beta receptors, Smad2 and Smad3 become phosphorylated and form heteromeric complexes with Smad4. Thereafter, these activated Smad complexes translocate to the nucleus, where they may direct transcriptional responses (2). Phosphorylation of Smad2 on Ser465 and Ser467 is required for Smad2/Smad4 complex formation and TGF-beta signaling (3).

Applications:
