SARA protein | i.e. Smad anchor for receptor activation protein, binding site for co-modulator Smad4, modulates self-association of partially phosphorylated Smad2 preventing premature release of monophosphorylated substrate, interaction with Smad2 via the Smad2 MH2 domain | Homo sapiens | |
TGF-beta | binds to and activates TbetaRI receptor kinase that phosphorylates Smad2 | Homo sapiens |
