Nesprin 1 (Nesp1)

Enaptin is a nuclear envelope protein found in human myocytes and synapses, which is made up of 8,797 amino acids. Post-translational amino acid modifications can be possible. Enaptin is involved in the maintenance of nuclear organization and structural integrity, tethering the cell nucleus to the cytoskeleton by interacting with the nuclear envelope and with F-actin in the cytoplasm.

Enaptin has a remarkable structure with a coiled alpha-helical region and a large beta-sheet region in the upper part and at least four alpha-helices spliced together, indicating the similarity with collagen. The structural integrity of Enaptin can be shown by determining whether the protein forms a condensed supramolecule.
