Lemd2 Gene Summary [Mouse]
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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Lemd2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
