Comments concerning this interaction

Source was embryos of wild-type fly line; proteins produced from endogenous genes.

The structure of the Drosophila 80S ribosome with accessory proteins solved by cryo-EM. Complex captured as 3828 pairwise interactions which do not necessarily reflect direct contact.

Source was live S2 cells; bait produced from transfected construct; prey produced from transfected construct.

To visualize the association of the 40S and 60S ribosomal subunits, a protein in each subunit was tagged with a complementary fragment of the fluorescent Venus protein. Proximity of the two proteins from different ribosomal subunits resulted in reconstitution of the fluorescent protein.

Comments concerning this interaction

Source was cell extract of S2 cell line; bait produced from transfected construct; prey produced from transfected construct.

The interaction of RpS18 and RpL11, as inferred by Venus fluorescence, was observed only in fractions containing 80S ribosomes.

The interaction of the small and large ribosomal subunits, as inferred from Venus bimolecular complementation, was increased in the presence of a translation elongation inhibitor (emetine).

The interaction of the small and large ribosomal subunits, as inferred from Venus bimolecular complementation, was decreased in the presence of a translation initiation inhibitors (puromycin, pactamycin and harringtonine).

Cell lysates were separated on sucrose density gradient to fractionate different ribosome populations. To examine the association of the 40S and 60S ribosomal subunits, a protein in each subunit was tagged with a complementary fragment of the fluorescent Venus protein. Proximity of the two proteins from different ribosomal subunits resulted in reconstitution of the fluorescent protein.
