High impact information on SMO

  • This effect of Shh was not mediated by Patched (Ptc) and Smoothened (Smo), the receptors that mediate effects of Shh in morphogenesis and commissural axon growth toward the floor plate [1].
  • We develop a model to study the effects of two forms of Shh used experimentally and propose a mechanism for Shh signal transduction based on a two-state model for the Ptc-Smo interaction [2].
  • We also describe genetic mapping of gli1, ptc, shh and smoothened in chickens and confirm by co-segregation analysis that none of these genes correspond to talpid3 [3].
  • Crescent encodes a protein that in its N-terminal half shows the characteristic invariant 9 cysteine residues of the cysteine-rich domain (CRD) found in the Frizzled family of proteins, in Smoothened and in Collagen XVIII [4].
