FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Bilateral symmetric nervous systems have special midline structures that establish a partition between the two mirror image halves. Some axons project toward and across the midline in response to long-range chemoattractants emanating from the midline. The product of this gene is a member of the immunoglobulin gene superfamily and encodes an integral membrane protein that functions in axon guidance and neuronal precursor cell migration. This receptor is activated by SLIT-family proteins, resulting in a repulsive effect on glioma cell guidance in the developing brain. A related gene is located at an adjacent region on chromosome 3. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]
PHENOTYPE: Mice homozygous for a reporter allele show altered axon guidance. Mice homozygous for a null allele die at birth showing aberrant axon pathfinding and cortical interneuron migration. Homozygotes for another null allele show neonatal death, aphagia, delayed lung maturation and bronchial hyperplasia. [provided by MGI curators]
