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).
WB Description
lem-2 encodes the ortholog of the vertebrate LEM2 and MAN1 proteins and contains a LEM domain which is a defining 40 amino acid motif shared by a family of nuclear envelope proteins; LEM family proteins bind to lamins and to the small inner nuclear membrane associated protein BAF; LEM-2 provides an anchor by which chromosomes are attached to the nuclear membrane; lem-2 together with the LEM domain protein emr-1/emerin, bind lmn-1/lamin and are required for viability and proper chromosome segregation; LEM-2 localizes to the nuclear membrane; lem-2 mutations also exhibit moderate hypersensitivity to DNA damage.
