Abstract:
A recent publication shows that two integrins, alpha6beta4 and alpha3beta1, interact with netrin-1, a protein best known for its role in axon guidance. Consistent with a role in pancreatic development in vivo, netrin is expressed together with these integrins in fetal pancreatic epithelium. The paper presents strong evidence that pancreatic epithelial cells adhere, spread and migrate on netrin-coated substrata through alpha6beta4. Data also indicate that alpha3beta1 mediates HGF-stimulated cell migration on netrin-coated substrata. These results indicate that netrins might have much broader functions than previously suspected.

Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction. It is...
