FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is a member of a conserved family of genes that share a common DNA-binding domain, the T-box. T-box genes encode transcription factors involved in the regulation of numerous developmental processes. In mouse, the ortholog of this gene is expressed in the cerebral cortex, hippocampus, amygdala and olfactory bulb and is thought to play an important role in neuronal migration and axonal projection. In mouse, the C-terminal region of this protein was found to be necessary and sufficient for association with the guanylate kinase domain of calcium/calmodulin-dependent serine protein kinase.

PHENOTYPE: Mice homozygous for a targeted null allele fail to feed and die on the second postnatal day displaying disrupted forebrain morphology and a hypoplastic olfactory bulb that lacks normal mitral and tufted cells and shows a striking reduction in mature olfactory bulb projection neurons.
