Absence of interaction between the 165-kDa fibronectin-binding protein involved in mouse odontoblast differentiation and vinculin.

Previous data suggested that matrix could control the organization of microfilaments in differentiating odontoblasts and that this process involved a complex of fibronectin-165-kDa membrane protein-vinculin. The use of two different gel systems and microsequence analysis demonstrated that two distinct 165-kDa proteins interact, one with fibronectin and the other with vinculin.
