Abstract We have studied the Mos1 transposase encoded by the transposable element mariner. This transposase is a member of the “D,D(35)E” superfamily of proteins exhibiting the motif D,D(34)D. It is not known whether this transposase, or other eukaryote transposases manifesting the D,D(35)E domain, functions in a multimeric form. Evidence for oligomerization was found in the negative complementation of Mos1 by an EMS-induced transposase mutation in the catalytic domain. The transposase produced by this mutation has a glycine-to-arginine replacement at position 292. The G292R mutation strongly interferes with the ability of wild-type transposase to catalyze excision of a target element. Negative complementation was also observed for two other EMS mutations, although the effect was weaker than observed with G292R. Results from the yeast two-hybrid system also imply that Mos1 subunits interact, suggesting the possibility of subunit oligomerization in the transposition reaction. Overproduction of Mos1 subunits through an hsp70 promoter also inhibits excision of the target element, possibly through autoregulatory feedback on transcription or through formation of inactive or less active oligomers. The effects of both negative complementation and overproduction may contribute to the regulation of mariner transposition.

Interacting Domain

Using a yeast two-hybrid system, we identified a novel protein which interacts with ras p21. This protein shares 69% amino acid homology with ral guanine nucleotide dissociation stimulator (ralGDS), a GDP/GTP exchange protein for ral p24. We designated this protein RGL, for ralGDS-like. Using the yeast two-hybrid system, we found that an effector loop mutant of ras p21 was defective in interacting with the ras p21-interacting domain of RGL, suggesting that this domain binds to ras p21 through the effector loop of ras p21. Since ralGDS contained a region highly homologous with the ras p21-interacting domain of RGL, we examined whether ralGDS could interact with ras p21. In the yeast two-hybrid system, ralGDS failed to interact with an effector loop mutant of ras p21. In insect cells, ralGDS made a complex with v-ras p21 but not with a dominant negative mutant of ras p21. ralGDS interacted with the GTP-bound form of ras p21 but not with the GDP-bound form in vitro. ralGDS inhibited both the GTPase-activating activity of the neurofibromatosis gene product (NF1) for ras p21 and the interaction of Raf with ras p21 in vitro. These results demonstrate that ralGDS specifically interacts with the active form of ras p21 and that ralGDS can compete with NF1 and Raf for binding to the effector loop of ras p21. Therefore, ralGDS family members may be effector proteins of ras p21 or may inhibit interactions between ras p21 and its effectors.
