General description
Nesprin-2 (UniProt: Q6ZWQ0; also known as KASH domain-containing protein 2, KASH2, Nuclear envelope spectrin repeat protein 2, Nucleus and actin connecting element protein, Protein NUANCE, Synaptic nuclear envelope protein 2, Syne-2) is encoded by the Syne2 gene (Gene ID: 319565) in murine species. Nesprin-2 is a single-pass type IV membrane protein with a large cytoplasmic domain (aa 1-6823), a transmembrane domain (aa 6824-2844), and a perinuclear space domain (aa 6845-6874). It contains two calponin-homology domains (aa 31-136 and 183-288) and fifty-six spectrin repeats. Its actin-binding region is localized in amino acids 1-286. Nesprin-2 is a multi-isomeric modular protein that forms a linking network between organelles and the actin cytoskeleton to maintain the subcellular spatial organization. It is a core component of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex that is involved in the connection between the nuclear lamina and the cytoskeleton. The nucleocytoplasmic interactions established by the LINC complex play an important role in the transmission of mechanical forces across the nuclear envelope and in nuclear movement and positioning. Three different isoforms of Nesprin-2 have been described that are produced by alternative splicing. Different isoform patterns are found in the different compartments of the cell. Nesprin-2 levels are shown to be down-regulated in cancer cells. Nesprin-2 knockdown cells exhibit a defective nuclear translocation of c-Fos and Smad 2/3. Mutations in Syne2 gene have been linked to Emery-Dreifuss muscular dystrophy 5 (EDMD5), an autosomal dominant form of degenerative myopathy. (Ref.: Zhang, Q., et a; (2019). Curr. Biol. 29(17); 2826-2839; Kelkar, P., et al. (2015). Nucleus. 6(6); 479-489; Luxton, GWG., et al. (2010). Science. 329(5994); 956-959).
