A selection fit mechanism in BMP receptor IA as a possible source for BMP ligand-receptor promiscuity
Plos One, 5:e13049-e13049, 2010

PubMed Abstract: Members of the TGF-β superfamily are characterized by a highly promiscuous ligand-receptor interaction as is readily apparent from the numeral discrepancy of only seven type I and five type II receptors available for more than 40 ligands. Structural and functional studies have been used to address the question of how specific signals can be deduced from a limited number of receptor combinations and to unravel the molecular mechanisms underlying the protein-protein recognition that allow such limited specificity.
