Name  Lamin Tail Domain Short Name  Lamin_tail_dom
Type  Domain Description  Intermediate filaments (IF) are primordial components of the cytoskeleton and the nuclear envelope []. They generally form filamentous structures 8 to 14 nm wide. IF proteins are members of a very large multigene family of proteins which has been subdivided in five major subgroups, type I: acidic cytokeratins, type II: basic cytokeratins, type III: vimentin, desmin, glial fibrillary acidic protein (GFAP),peripherin, and plasticin, type IV: neurofilaments L, H and M, alpha-internexin and nestin, and type V: nuclear lamins A, B1, B2 and C. The lamins are components of thenuclear lamina, a fibrous layer on the nucleoplasmic side of the inner nuclear membranethat may provide a framework for the nuclear envelope and may interact with chromatin.All IF proteins are structurally similar in that they consist of a central rod domain arranged in coiled-coil alpha-helices, with at least two short characteristic interruptions; a N-terminal non-helical domain (head) of variable length; and a C-terminaldomain (tail) which is also non-helical, and which shows extreme length variation between different IF proteins. The C-terminal domain has been characterised for the lamins [].The lamin-tail domain (LTD), which has an immunoglobulin (Ig) fold, is found in nuclear lamins, Chlo1887 from Chloroflexus, and several bacterial proteins where it occurs with membrane associated hydrolases of the metallo-beta-lactamase, synaptojanin, and calcineurin-like phosphoesterase superfamilies [].
