Focal adhesion kinase is involved in rabies virus infection through its interaction with viral phosphoprotein P.

ABSTRACT:

Unlabelled

The rabies virus (RABV) phosphoprotein P is a multifunctional protein: it plays an essential role in viral transcription and replication, and in addition, RABV P has been identified as an interferon antagonist. Here, a yeast two-hybrid screen revealed that RABV P interacts with the focal adhesion kinase (FAK). The binding involved the 106-to-131 domain, corresponding to the dimerization domain of P and the C-terminal domain of FAK containing the proline-rich domains PRR2 and PRR3. The P-FAK interaction was confirmed in infected cells by coimmunoprecipitation and colocalization of FAK with P in Negri bodies. By alanine scanning, we identified a single mutation in the P protein that abolishes this interaction. The mutant virus containing a substitution of Ala for Arg in po
