Nuclear lamins are composed of the type V intermediate filament proteins. Often referred to as nucleoskeletal proteins they play a key role in nuclear integrity, positioning of nuclear pores, and overall nuclear size and shape. They also play several key functional roles in the maintenance and propagation of the genome--replication, transcription-- as well as the disassembly and reassembly of the nucleus during cell division. In vitro studies have shown that dimers are the basic building blocks of higher order lamin structures and in low concentrations lamins are distributed throughout the nucleoplasm. In humans, there are two types of lamins: A-type lamins (lamins A and C), found primarily in differentiated cells, and B-type lamins (lamins B1 and B2), found in all nucleated cells. Nuclear lamins are involved in a number of essential nuclear functions, including nuclear envelope assembly and disassembly during cell division, DNA synthesis, transcription, and apoptosis. Nuclear lamins have been found to co-localize with DNA synthesis sites.
