Identify the correct ligands in both receptor serine kinase pathway.

 

#Unit 5. Developmental Biology
  1. Smads 2 and 3 are activated by the BMP family of TGF- β factors, whereas the receptors binding activin, Nodal, and the TGF- β family phosphorylate Smads 1 and 5.

  2. Smads 1 and 5 are activated by the BMP family of TGF- β factors, whereas the receptors binding activin, Nodal, and the TGF- β family phosphorylate Smads 2 and 3.

  3. Smads 1 and 5 are activated by the BMP family of TGF- β factors, whereas the receptors binding activin, Nodal, and the TGF- β family phosphorylate only smad 4.

  4. Smads 4 are activated by the BMP family of TGF- β factors, whereas the receptors binding activin, Nodal, and the TGF- β family phosphorylate all smads 1,2,3,5.
