lamins
Sunday 13 July 2003
Lamins constitute a family of polypeptides composing the proteinaceous layer apposed to the inner nuclear membrane. In mammals, 3 lamins, A (LMNA), B (LMNB), and C (encoded by LMNA), have been described, with molecular weights ranging from 60,000 to 78,000. Lamins A and C but not lamin B have close sequence homology. Lamins can be classified with the intermediate filament (IF) polypeptides.
