Probable transcription factor that plays a role in configuring the spinal circuits controlling stride in vertebrates. Involved in neuronal specification within a specific subdivision of spinal cord neurons and in the development of a coordinated locomotor network controlling limb movements. May regulate transcription during sexual development (By similarity). DMA domain interacts with ubiquitin. DMRT3 is a marker for a subset of spinal cord neurons (dI6). Belongs to the DMRT family.
