[[http://www.uniprot.org/uniprot/VIME_HUMAN VIME_HUMAN]] Vimentins are class-III intermediate filaments found in various non-epithelial cells, especially mesenchymal cells. Vimentin is attached to the nucleus, endoplasmic reticulum, and mitochondria, either laterally or terminally.<ref>PMID:21746880</ref> Involved with LARP6 in the stabilization of type I collagen mRNAs for CO1A1 and CO1A2.<ref>PMID:21746880</ref>

== Publication Abstract from PubMed ==

Intermediate filaments (IFs) are essential cytoskeletal components in metazoan cells. They assemble from elementary dimers that are built around the central alpha-helical coiled-coil rod domain representing the IF 'signature'. The rod consists of two similarly-sized parts, coil 1 and coil 2, connected by a non-alpha-helical linker L12. Coil 2 is absolutely conserved in length across all IF types and was initially predicted to consist of a short coiled-coil segment 2A based on a heptad pattern of hydrophobic residues, another linker L2 and a coiled-coil segment 2B. Here we present the crystal structure of human vimentin fragment including residues 261-335 i.e. approximately the first half of coil 2. The N-terminal part of this fragment reveals a parallel alpha-helical bundle characterized by 3.5 consecutive hendecad repeats. It is immediately followed by a regular left-handed coiled coil. The distinct non-helical linker L2 is therefore not observed. Together with the previously determined crystal structure of the major part of segment 2B (Strelkov et al., 2002), we can now build a complete atomic model of the 21nm long vimentin coil 2 dimer being a relatively rigid rod.
