FAK phosphorylation sites mapped by mass spectrometry

The protein tyrosine kinase, focal adhesion kinase (FAK), is a central regulator of integrin-mediated signaling ([Mitra et al., 2005][1]; [Parsons, 2003][2]; [Schlaepfer and Mitra, 2004][3]). FAK is present in focal adhesions, adhesive structures that mediate attachment of cells to the extracellular
