"The C-terminal DSP domain induced phosphorylation of occludin Ser(490) and focal adhesion kinase (FAK) Ser(722) and Tyr(576). Coexpression of DSP occludin and FAK was detected in dental mesenchymal cells during tooth development. Occludin physically interacts with FAK and occludin and FAK phosphorylation can be blocked by DSP and occludin antibodies."xsd:string
