Putative transcription factor, which may be involved in patterning of central nervous system and pancreas. Expressed in the developing CNS and gastro-intestinal tract. In the developing embryo, it is confined to the gut and caudal hindbrain. In caudal hindbrain, it is specifically expressed in a subpopulation of differentiating V2 neurons. Not detected prior to 12.5 dpc and is not found in motor nuclei. At 12.5 dpc, it is expressed in the ventral medial aspect of the medullary reticular formation (MDR). At 16.5 dpc, expression is confined to the gigantocellular nucleus, a nucleus that is part of the MDR. In addition to the CNS, it is also expressed in the developing gut, in duodenal and glandular stomach endoderm and, at the end of gestation becomes restricted to the base of the gastric units in the glandular stomach. Expressed at very low level in the pancreatic epithelium. Expressed in the pancreas at 15.5 dpc.
