Receptor

  1. active peptide forms a hetero- or homodimer
  2. binds to a specific TGF-β Type II receptor
  3. Type II receptor then recruits a TGF-β Type I receptor
  4. phosphorylates it via its serine/threonine kinase domain
  5. phosphorylated Type I receptors then phosphorylate receptor-associated Smad proteins (R-Smads), including Smad1/5 and Smad2/3
  • Type II receptor - MlTgfRII
  • Type I receptors - MlTgfRIa, MlTgfRIb, and MlTgfRIc

Intracellular Signaling

  • R-Smad proteins are composed of two main functional domains
    • Mad-homology domains 1 and 2 (MH1 and MH2)
  • Smad1/5 - associated with BMP-like signalling.
  • Smad2/3 - associated with TGF-β-like signaling.

OMIM

About OMIM "Online Mendelian Inheritance in Man OMIM is a comprehensive, authoritative, and timely compendium of human genes and genetic phenotypes. The full-text, referenced overviews in OMIM contain information on all known mendelian disorders and over 12,000 genes. OMIM focuses on the relationship between phenotype and genotype. It is updated daily, and the entries contain copious links to other genetics resources." OMIM
