Class: Nuclear_Lamina


Super Classes



definitionMeshwork of extremely fine filaments composed of polypeptides called lamins that run parallel with the inner surface of the nuclear envelope (Peters, Palay and Webster, 1991).
definitionThe fibrous, electron-dense layer lying on the nucleoplasmic side of the inner membrane of a cell nucleus, composed of lamin filaments. The polypeptides of the lamina are thought to be concerned in the dissolution of the nuclear envelope and its re-formation during mitosis. The lamina is composed of lamin A and lamin C filaments cross-linked into an orthogonal lattice, which is attached via lamin B to the inner nuclear membrane through interactions with a lamin B receptor, an IFAP, in the membrane (Gene Ontology).
