摘要: Mutations in genes encoding widely expressed nuclear envelope proteins often lead to diseases that manifest specific tissues. Lamina-associated polypeptide 1 (LAP1) is an integral protein of the inner membrane most cells and Within envelope, LAP1 interacts physically with lamins, torsinA emerin, suggesting it may serve as a key node for transducing signals across membrane. Indeed, recent vivo studies genetically modified mice strongly support functional links between both (in neurons) emerin muscle). These suggest tissue-selective caused by mutations result, at least part, from selective disruption discrete complexes.
