FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a LEM domain-containing transmembrane protein of the inner nuclear membrane. The protein is involved in nuclear structure organization and plays a role in cell signaling and differentiation. Mutations in this gene result in Cataract 46, juvenile-onset. Multiple transcript variants have been found for this gene. [provided by RefSeq, Feb 2017]
PHENOTYPE: Homozygotes for a gene-trapped allele die by E11.5 exhibiting reduced embryo size and cell density in neural tissue and mesenchyme, underdeveloped cardiac and neural tissue, and hyperactivation of MAPK and AKT signaling. Heterozygotes show a modest delayin cardiotoxin-induced muscle regeneration. [provided by MGI curators]
