High impact information on smad2

  • PPM1A dephosphorylates and promotes nuclear export of TGFbeta-activated Smad2/3 [1].
  • Mutations in oep eliminate the response to Squint and Cyclops overexpression but are suppressed by expression of Activin and activated forms of the type I receptor ActRIB and Smad2 [2].
  • The transcription factors Fast-1 and Mixer are important terminal components of Smad2-mediated TGF-beta signal transduction [3].
  • The proteins examined include activin subunits (betaA and betaB), activin-binding protein (follistatin), activin type II receptors (type IIA and IIB), the type I activin receptor-like kinases (ALK1-like, ALK2-like, and ALK4-like), and the intracellular activin signaling molecules (Smad2, Smad3, Smad4, and Smad7) [4].
  • In summary, our analyses point out differences of Smad3b and Smad2 functions in zebrafish and provide the first link of smad3 and smad7 function in context of vertebrate development [5].
 

Anatomical context of smad2

 

Other interactions of smad2

  • In contrast to Smad1, neither Smad2 nor Smad5 caused a detectable effect when expressed as full-length molecules suggesting that these latter two Smads are more dependent on activation by the cognate TGFbeta ligands [6].
  • Overexpression of truncated smad2 in cyclops mutant embryos leads to a rescue of the eye and floorplate defects [7].
  • We report here the cloning, characterization and genomic mapping of smad2, smad3 and smad4 from the zebrafish, Danio rerio [7].
  • Cloning and characterization of zebrafish smad2, smad3 and smad4 [7].
