Summary: Enables chromatin DNA binding activity and lamin binding activity. Involved in several processes, including microtubule organizing center organization; nuclear membrane reassembly; and response to X-ray. Located in chromosome and nuclear envelope. Used to study Emery-Dreifuss muscular dystrophy and cataract 46 juvenile-onset. Human ortholog(s) of this gene implicated in Buschke-Ollendorff syndrome and cataract 46 juvenile-onset. Orthologous to human LEMD3 (LEM domain containing 3) and LEMD2 (LEM domain nuclear envelope protein 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

these results clearly show that Ce-emerin and LEM-2 have additional roles in specific tissues, including striated muscle and smooth muscle.
Title: Ce-emerin and LEM-2: essential roles in Caenorhabditis elegans development, muscle function, and mitosis.
LEM-2 is localized to the nuclear membrane in every cell of C. elegans embryos. The genes in LEM-2 subdomains tend to be inactive, while those in gaps tend to be active.
Title: Caenorhabditis elegans chromosome arms are anchored to the nuclear membrane via discontinuous association with LEM-2.
