Also known as: Lem2; NET25
Summary: Predicted to enable chromatin DNA binding activity. Involved in heart formation; negative regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction; and neurogenesis. Acts upstream of or within negative regulation of MAPK cascade and skeletal muscle cell differentiation. Located in nuclear membrane. Is expressed in several structures, including heart; leg muscle; liver; nephric duct; and neural tube. Used to study cardiomyopathy. Human ortholog(s) of this gene implicated in cataract 46 juvenile-onset. Orthologous to human LEMD2 (LEM domain nuclear envelope protein 2). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Ubiquitous expression in adrenal adult (RPKM 61.9), ovary adult (RPKM 61.0) and 28 other tissues See more

we expressed a LEMD2 transgene alone or in combination with lamin C in these cells and observed no restoration of peripheral heterochromatin in either case. We conclude that in contrary to the B-tether, the A-tether has a more intricate composition and consists of multiple components that presumably vary, at differing degrees of redundancy, between cell types and differentiation stages

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
