(increases, SMAD1/SMAD4 Activity)
Evidence: Phosphorylation of the C-terminal serine residues in R-Smads by type I receptor kinases is a crucial step in TGF-b family signalling (Abdollah et al., 1997; Macias-Silva et al., 1996; Souchelnytskyi et al., 1997). The two most C-terminal serine residues become phosphorylated and, together with a third, non-phosphorylated serine residue, form an evolutionarily conserved SSXS motif in all R-Smads.... TGF-b and activin receptors phosphorylate Smad2 and Smad3, and BMP receptors phosphorylate Smad1, ...

BMPR1B
(directlyIncreases, SMAD1 Activity)
Evidence: BMP receptors activate Smad1, Smad5, and Smad8 (called BR-Smads in this review) whereas Smad2 and Smad3 are phosphorylated by the activin of Tgfbeta recepetors ALK3 and ALK6 can activate all three BR-Smads but ALK2 only phophorylates SMAD1 and SMAD5
