WebIn somatic cells, the main proteins of the nuclear lamina are lamins A, C, B1, and B2. Citation1,Citation2Lamins A and C (the A-type lamins) are alternatively spliced isoforms of LMNA; they are expressed late in development and are found in most differentiated cells.

Web13 feb. 2024 · The nuclear lamina is essential for the maintenance of nuclear shape and mechanics. Mutations in lamin genes have been identified in a heterogeneous spectrum … The nuclear lamina is assembled by interactions of two lamin polypeptides in which the α-helical regions are wound around each other to form a two stranded α-helical coiled-coil structure, followed by a head-to-tail association of the multiple dimers. The linearly elongated polymer is extended laterally by a side-by-side association of polymers, resulting in a 2D structure underlying the nuclear envelope. Next to providing mechanical support to the nucleus, the nuclear lamina p…
Web11 mrt. 2024 · The nuclear lamina protects the nucleus from mechanical stress and mediates nucleo-cytoskeletal coupling. Lamins form a scaffold that partially tethers chromatin at the nuclear envelope. The nuclear lamina also stabilises protein-protein interactions involved in gene regulation and DNA repair.
