Comparison of diffusion rates and mobility of FGFR1-EGFP in the presence of known interacting proteins and controls that do not interact
| Protein | Recovery rate t1/2 (s) | Mobile population (%) |
|---|---|---|
| FGFR1-pcDNA (n = 21) | 8.607 ± 0.917 | 38.531 ± 2.113 |
| FGFR1-CBP (n = 9) | 9.751 ± 2.06 | 49.091 ± 0.326 |
| FGFR1-RSK1 (n = 30) | 1.273 ± 0.341 | 73.342 ± 2.202 |
| FGFR1-RSKmt (n = 21) | 9.556 ± 1.75 | 54.163 ± 3.48 |
| FGFR1(TK-)-pcDNA (n = 25) | 0.807 ± 0.119 | 46.502 ± 6.585 |
| FGFR1(TK-)-RSK1 (n = 30) | 0.764 ± 0.154 | 53.037 ± 6.124 |
Average values are given for the indicated number of cells, which was calculated by averaging the t1/2 or mobility value for each cell fit by nonlinear regression analysis. Error is expressed as SEM t1/2 and mobile population of FGFR1 in the presence of cotransfected RSK1 (but not CBP) were significantly different from FGFR1-pcDNA (p < 0.001). No significant differences between FGFR1(TK-) cotransfected with control plasmid (pcDNA) or RSK1 were found.
