Lamins

proteins that form the nuclear lamina, a polymeric structure intercalated between chromatin and the inner nuclear envelope. Lamins a and c (70 and 60 kd respectively) have c terminal sequences homologous to the head and tail domains of keratins, their peptide maps are similar and significantly different from that of lamin B (67 kd), although there are some common epitopes.
