Vinculin (VCL), a ubiquitously expressed actin-binding cytoskeletal protein, is involved with the cytoplasmic adhesion of cell-cell and cell-extracellular matrix. It is composed of an N-terminal globular head connected via a short polyproline-rich linker sequence to the C-terminal tail portion. An intramolecular association between the head and tail hides many ligand-binding sites in the protein.

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: VCL (vinculin), a regulator of cell adhesion, is localized at the cytoplasmic region of cell-matrix and cell-cell adhesions to regulate various biological processes, including embryogenesis, wound healing and maintenance of tissue integrity. It has the ability to suppress cell migration and can modulate signaling pathways involved in apoptosis. During cell-cell and cell-extracellular matrix adhesion, VCL binds to the a-actinin, an F-actin bundling protein and talin. Upon binding, it stimulates the assembly of these specialized cellular junctions.
