nuclear lamina


nuclear lamina
A fibrous protein network lining the inner surface of the nuclear envelope. The extent to which this system also provides a scaffold within the nucleus is controversial. Proteins of the lamina are lamins A, B and C, which have sequence homology to proteins of intermediate filaments.
