Fig. 5. (A) Domain structure of pp60Src and amino acid sequence of the SH2 domain
(from mouse neuronal Src). (B) Schematic representation of the YFP-SH2 and
YFP-dSH2 constructs. (C) Live-cell recording of SV80 cells transfected with
YFP-SH2. The fusion protein localizes to FAs only weakly and shows a high
cytoplasmic background. (D) Live-cell recording of SV80 cells transfected with
YFP-dSH2. Note the distinct FA staining and relatively low cytoplasmic
background. (E) Fixed cell transfected with YFP-SH2, showing loss of FA
localization. (F) Fixed, YFP-dSH2 transfected cell, showing retention of FA
labeling after fixation. Bar, 10 µm.
