The orderly arrangement of neuronal cell bodies and axonal projections
generated during nervous system development requires precise spatio-t
emporal control of the expression and activity of cell adhesion recept
ors. Recent evidence suggests that homeobox genes, an important class
of developmental control genes, many of which are preferentially expre
ssed in developing nervous tissue, play prominent roles in the regulat
ion of expression of these molecules. We have characterised two mouse
homeobox genes, named Cux and Phox2, the products of which bind to and
regulate the promoter of the Ncam gene in vitro. Its highly specific
expression pattern suggests that Phox2; besides regulating Ncam, may b
e a determinant of the noradrenergic phenotype.
