WebDec 5, 2011 · Lamins are alternatively spliced to create multiple isoforms. The genomes of mammals encode three lamin genes, LMNA, LMNB1 and LMNB2, which collectively express at least seven protein isoforms. LMNA is alternatively spliced producing at least four isoforms: the two major isoforms lamin A and C, and the two minor isoforms C2 and AΔ10. Lamins, also known as nuclear lamins are fibrous proteins in type V intermediate filaments, providing structural function and transcriptional regulation in the cell nucleus.
