The nuclear lamins are fiborous structural proteins found in the nucleus of eukaryotic cells. They carry out multiple functions involved in the structural organisation of the cell nucleous, including mechanical support of the nuclear pores, involved in molecular transport within the cell, to the organisation of chromoatin, DNA replication and cell division.
Composition
the lamins are copmprised of the protein stuture called intermediate fillament. This is a fillementous strucutral protein involved in the cytoskeleton, playing roles in organelle positioning, cell shape and movement and iter and intra cellular transport. the intermediate filament is found in the cytoplasm and in the cell nucleous, mainly used for mechanical strengh. they are strong stable molecuels which are couiled in shape. they are 10nm in diameter and are a polymer structure. they are also found in keterins.
DNA replication and cell division
In DNA replication nuclear lamins are involved in stuructural support, providing a structural network
