MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene contains a homeobox domain and may be involved in the morphogenesis of the central nervous system. This gene is found on chromosome 20 near NKX2-4, and these two genes appear to be duplicated on chromosome 14 in the form of TITF1 and NKX2-8. The encoded protein is likely to be a nuclear transcription factor. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mutants die within a few days of birth with severe hyperglycemia due to arrested differentiation of pancreatic beta cells. Mutant embryos exhibit retarded oligodendrocyte differentiation and a virtual loss of serotonergic neurons at the r2 level of the hindbrain. [provided by MGI curators]
