Biological context of VCL

 

Anatomical context of VCL

  • It is thus proposed that the interactions of the dense plaque with myofilaments or with the membrane do not depend on the presence of vinculin in the plaque [14].
  • The localization of vinculin and talin in embryonic chicken gizzards indicated that both are primarily cytoplasmic during the first 2 embryonic weeks [14].
  • We discuss the possible roles of vinculin and talin in the assembly of membrane-bound dense plaques during the different phases of smooth-muscle development [14].
  • Immunofluorescence and immunoelectron-microscopic labeling revealed that both proteins are associated with membrane-bound dense plaques in muscle cells; however, the most intense labeling for vinculin was located rather closer to the membrane than that for talin [14].
  • IpaA, a Shigella protein secreted upon cell contact, binds to the focal adhesion protein vinculin and is required for efficient bacterial uptake [1].
 

Associations of VCL with chemical compounds

  • To identify the talin binding domain in vinculin, we expressed the NH2-terminal region of the molecule encoded by two closely similar, but distinct vinculin cDNAs, using an in vitro transcription translation system [15].
  • A considerably (3 times) larger fraction of the talin than of the vinculin molecules was found to be phosphorylated on tyrosine [16].
  • The extent of tyrosine modification in talin was compared to that in vinculin, the other focal adhesion component previously found to contain enhanced levels of phosphotyrosine in various retrovirus-transformed cells [16].
  • We show that conformational changes in the head, tail and proline-rich domains are linked structurally and thermodynamically, and propose a combinatorial pathway to activation that ensures that vinculin is activated only at sites of cell adhesion when two or more of its binding partners are brought into apposition [17].
  • Moreover, rhodamine- or fluorescein-conjugated vinculin, when added to these preparations, became specifically associated with the focal contacts regardless of whether the latter were pretreated with fragmin or not [18].

Other interactions of VCL

  • Unlike other focal adhesion proteins, such as vinculin and talin, this filamin isoform is apparently not localized evenly throughout the entire area of adhesion, being absent from or greatly reduced in the distal portion of the area [26].
  • Fluorescence photobleaching recovery analyses performed with living cells microinjected with fluorescently labeled actin, vinculin, and alpha-actinin indicate that each of these proteins maintains a dynamic equilibrium between a soluble cytoplasmic pool and a membrane-bound fraction [27].
  • Paxillin: a new vinculin-binding protein present in focal adhesions [3].
  • First, both the purified 30-kDa tail fragment and a fusion protein containing tail domain, vinculin residues 884-1066, protect purified 95-kDa head domain from cleavage by protease V8 in a specific, dose-dependent manner [28].
  • Integrin localization was compared with that of its putative cytoskeletal-associated and extracellular matrix ligands, talin and vinculin and fibronectin and laminin, respectively [29].
