Common NameEmerin
DescriptionEmerin is a member of the integral membrane protein class, specifically belonging to the LEM (LAP2/emerin/MAN1) domain family. Chemically, emerin is characterized by its interaction with A-type lamins at the inner nuclear membrane (INM) through two independent binding sites, forming a dense meshwork that is crucial for maintaining nuclear structure and function (PMID:40950172 ). Its role extends to the regulation of chromatin domains and gene expression, as tubular lamin- and emerin-lined nuclear envelope invaginations isolate these domains (PMID:41004039 ). Emerin is also involved in cellular responses to mechanical stress, with studies indicating that mechanically-induced premature senescence correlates with decreased emerin levels (PMID:40999893 ). Furthermore, mutations in emerin or lamin A/C are implicated in Emery-Dreifuss muscular dystrophy (EDMD), highlighting its significance in muscle integrity (PMID:41040396 ). The loss of emerin, along with lamin B1, has been shown to mark ruptured nuclear blebs, suggesting its involvement in nuclear stability (PMID:41047936 ). Overall, emerin's structural properties and interactions with other nuclear envelope proteins underscore its critical role in nuclear architecture and cellular signaling pathways.
