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 family of discs large (DLG) homologs, a subset of the membrane-associated guanylate kinase (MAGUK) superfamily. The MAGUK proteins are composed of a catalytically inactive guanylate kinase domain, in addition to PDZ and SH3 domains, and are thought to function as scaffolding molecules at sites of cell-cell contact. The protein encoded by this gene localizes to the plasma membrane and cytoplasm, and interacts with components of adherens junctions and the cytoskeleton. It is proposed to function in the transmission of extracellular signals to the cytoskeleton and in the maintenance of epithelial cell structure. Alternative splice variants have been described but their biological nature has not been determined. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a null allele exhibit growth retardation, hydroencephaly, abnormal brain morphology, abnormal neurogenesis, kidney cysts, ureter defects, and abnormal kidney morphology. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified a C to T transition at base pair 24974355 in the Genbank genomic region NC_000080 for the Dlg5 gene on chromosome 14 (GTAACTACCA ->GTAACTATCA). Three transcripts of the Dlg5 gene are displayed on Ensembl. The mutation is located within intron 18 of the transcript that encodes isoform 2, eight nucleotides from exon 18. The Dlg5 transcript contains up to 32 total exons. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Dlg5 gene encodes a predicted 1921 amino acid protein that is a member of the family of discs large (DLG) homologs, a subset of the membrane-associated guanylate kinase (MAGUK) superfamily. The MAGUK proteins are composed of a catalytically inactive guanylate kinase domain, in addition to PDZ and SH3 domains, and are thought to function as scaffolding molecules at sites of cell-cell contact. The protein encoded by Dlg5 localizes to the plasma membrane and cytoplasm, and interacts with components of adherens junctions and the cytoskeleton. It is proposed to function in the transmission of extracellular signals to the cytoskeleton and in the maintenance of epithelial cell structure.
