The type V intermediate filament lamins are the principal components of the nuclear matrix, including the nuclear lamina. Lamins are divided into A-type and B-type, which are encoded by three genes, LMNA, LMNB1, and LMNB2. The alternative splicing of LMNA produces two major A-type lamins, lamin A and lamin C. Previous studies have suggested that lamins are involved in cancer development and progression. This evidence concerns the gene LMNB2 and cancer.
