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 basic helix-loop-helix transcription factor family. Members of this family contain two highly conserved and functionally distinct domains: the basic domain targets sequence-specific DNA binding, while the helix-loop-helix domain facilitates protein interaction. Studies of a related gene in mouse suggest that the encoded protein may function as a transcriptional repressor in the pancreas and brain, and that it is required for normal retinal function.

PHENOTYPE: Mice homozygous for a knock-out allele display a severe deficit in retinal activity characterized by improper retinal rod bipolar cell maturation, loss of the scotopic ERG b-wave, and a significant increase in inner nuclear layer (INL) cell apoptosis. [provided by MGI curators]
