  • FunctionTranscription factor. Involved in SHH-dependent neural patterning. Together with NKX2-2 and NKX6-1 acts to restrict the generation of motor neurons to the appropriate region of the neural tube. Belongs to the class I proteins of neuronal progenitor factors, which are repressed by SHH signals. Involved in the transcriptional repression of MNX1 in non-motor neuron cells.
  • Sequence similaritiesBelongs to the TALE/IRO homeobox family.
    Contains 1 homeobox DNA-binding domain.
  • Cellular localizationNucleus.
