| T1 |
0-88 |
Sentence |
denotes |
A direct interaction between G-protein beta gamma subunits and the Raf-1 protein kinase. |
| T2 |
89-209 |
Sentence |
denotes |
Raf-1 is a serine/threonine protein kinase positioned downstream of Ras in the mitogen-activated protein kinase cascade. |
| T3 |
210-431 |
Sentence |
denotes |
Using a yeast two-hybrid strategy to identify other proteins that interact with and potentially regulate Raf-1, we isolated a clone encoding the carboxyl-terminal half of the G beta 2 subunit of heterotrimeric G-proteins. |
| T4 |
432-562 |
Sentence |
denotes |
In vitro, purified G beta gamma subunits specifically bound to a GST fusion protein encoding amino acids 1-330 of Raf-1 (Raf/330). |
| T5 |
563-737 |
Sentence |
denotes |
Binding assays with truncation mutants of GST-Raf indicate that the region located between amino acids 136 and 239 is a primary determinant for interaction with G beta gamma. |
| T6 |
738-949 |
Sentence |
denotes |
In competition experiments, the carboxyl terminus of beta-adrenergic receptor kinase (beta ARK) blocked the binding of G beta gamma to Raf/330; however, the Raf-1-binding proteins, Ras and 14-3-3, had no effect. |
| T7 |
950-1155 |
Sentence |
denotes |
Scatchard analysis of in vitro binding between Raf/330 and G beta gamma revealed an affinity of interaction (Kd = 163 +/- 36 nM), similar to that seen between G beta gamma and beta ARK (Kd = 87 +/- 24 nM). |
| T8 |
1156-1431 |
Sentence |
denotes |
The formation of native heterotrimeric G alpha beta gamma complexes, as measured by pertussis toxin ADP-ribosylation of G alpha, could be disrupted by increasing amounts of Raf/330, with an EC50 of approximately 200 nM, in close agreement with the estimated binding affinity. |
| T9 |
1432-1571 |
Sentence |
denotes |
In vivo complexes of Raf-1 and G beta gamma were isolated from human embryonic kidney 293-T cells transfected with epitope-tagged G beta 2. |
| T10 |
1572-1781 |
Sentence |
denotes |
The identification and characterization of this novel interaction raises several possibilities for signaling cross-talk between growth factor receptors and those receptors coupled to heterotrimeric G-proteins. |
