MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the LIM/homeodomain family of transcription factors. The encoded protein binds to the enhancer region of the insulin gene, among others, and may play an important role in regulating insulin gene expression. The encoded protein is central to the development of pancreatic cell lineages and may also be required for motor neuron generation. Mutations in this gene have been associated with maturity-onset diabetes of the young. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for a targeted null mutation fail to develop motor neurons and die by embryonic day 11.5 with abnormal heart and pancreas development. Mice heterozygous for an ENU mutation exhibit chronic otitis media and hearing loss. [provided by MGI curators]
