| 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.
