Homeobox protein DBX1 (Dbx1)

Could have a role in patterning the central nervous system during embryogenesis. Has an integral role in regulating the different phenotypic features that distinguish two big classes of ventral interneurons, V0 and V1 neurons.

Regulates the transcription factor profile, neurotransmitter phenotype, intraspinal migratory path and axonal trajectory of V0 neurons, features that differentiate them from an adjoining set of V1 neurons. .
