MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a nuclear outer membrane protein that binds cytoplasmic F-actin. This binding tethers the nucleus to the cytoskeleton and aids in the maintenance of the structural integrity of the nucleus. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]
PHENOTYPE: Homozygotes for one knock-out allele show normal myonuclear positioning of both synaptic and non-synaptic nuclei in skeletal muscle cells. Homozygotes for another knock-out allele exhibit a thickened epidermis and altered nuclear envelope architecture inprimary dermal fibroblasts and keratinocytes. Mice homozygous for a spontaneous mutation exhibit early retinal defects in photoreceptors, secondary Neurons, and muller glia. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified a C to A transversion at position 3934 of the Syne2 transcript, in exon 29 of 116 total exons (NM_001005510). Multiple transcripts are annotated in the Vega and Ensembl databases. The mutation causes a threonine to lysine change at amino acid 1242 of the encoded protein (NP_001005510). The mutation has been confirmed by DNA sequencing using the Sanger method (see trace files for B5639).

Protein Function and Prediction

The Syne2 gene encodes multiple isoforms of a protein known as Nesprin-2. The standard isoform is 6874 amino acids long. Nesprin-2 is a multi-isomeric modular protein which forms a linking network between organelles and the actin cytoskeleton to maintain the subcellular spatial organization. It is a component of SUN-protein-containing multivariate complexes also called LINC complexes, which link the nucleoskeleton and cytoskeleton by providing versatile outer nuclear membrane attachment sites for cytoskeletal filaments. Nesprin-2 connects nuclei to the cytoskeleton by interacting with the nuclear envelope and with F-actin in the cytoplasm. It is required for centrosome migration to the apical cell surface during early ciliogenesis. The cytoplasmic domain of the protein contains an actin-binding domain at residues 1-286, two CH domains at residues 31-136 and 183-288, followed by 17 spectrin repeats, and a highly hydrophobic nuclear envelope localization domain known as the KASH domain at residues 6815-6874 (Uniprot Q6ZWQ0). Heterozygous mutations in human SYNE2 cause Emery-Dreifuss muscular dystrophy (EDMD5; OMIM #612999).

The mutation is predicted to be probably benign by the PolyPhen-2 program.
