Emerin, together with MAN1, is a LEM domain-containing integral protein of the inner nuclear membrane in vertebrates. The function of MAN1 is not extensively known, but emerin is known to interact with nuclear lamins, barrier-to-autointegration factor (BAF), nesprin-1α, and a transcription repressor.

Emerin is a serine-rich nuclear membrane protein and a member of the nuclear lamina-associated protein family. It mediates membrane anchorage to the cytoskeleton. Dreifuss-Emery muscular dystrophy is an X-linked inherited degenerative myopathy resulting from mutation in the emerin gene.[1]

Clinical significance[edit]

Mutations in emerin cause X-linked recessive Emery-Dreifuss muscular dystrophy.

Moreover, recent research have found that the absence of functional emerin may decrease the infectivity of HIV-1. Thus, it is speculated that patients suffering from Emery-Dreifuss muscular dystrophy may have immunity to or show an irregular infection pattern to HIV-1.[2]

Interactions[edit]

Emerin has been shown to interact with YTHDC1,[3] ACTG2,[4] PSME1[3] and LMNA.[3][4][5][6]
