Vinculin is a cytoskeletal protein that plays an important role in the regulation of focal adhesions and embryonic development (1-4).
Three structural vinculin domains include an amino-terminal head, a short, flexible proline-rich region and a carboxy-terminal tail (1).
In the inactive state, the head and tail domains of vinculin interact to form a closed confirmation.
The open and active form of vinculin translocates to focal adhesions where it is thought to be involved in anchoring F-actin to the membrane and regulation of cell migration (2).
Phospholipid binding to the tail domain and subsequent phosphorylation of vinculin at Ser1033 and Ser1045 by PKC-alpha and Tyr100 and Tyr1065 by Src kinases weakens the head-tail interaction (5,6).
This change in vinculin allows the binding of a number of other proteins, including talin, alpha-actinin and paxillin, which disrupts the head-tail interaction and initiates the conformational change from the inactive to active state (2,4).
Vinculin deficiencies are associated with a decrease in cell adhesion and an increase in cell motility, suggesting a possible role in metastatic growth (7,8).
This is supported by a recently demonstrated relationship between decreased vinculin expression and increased carcinogenesis and metastasis in colorectal carcinoma (9).
