2.7.7.48 | expression of FLAG-tagged D-elp1 in Spodoptera frugiperda Sf9 cells using the baculovirus transfection system, and of His-tagged wild-type and mutant enzymes in Escherichia coli. Quantitative RT-PCR analysis for the expression levels of Dcr-2 and D-elp1 RNAs in S2 cells after depletion | Drosophila melanogaster |

2.7.7.48 | additional information | construction of D-elp1 protein mutants through (1-1252 aa) and the DELTAC (1-843aa) and DELTAN (844-1252 aa) deletions. D-elp1 depletion inhibits RNAi in S2 cells but does not affect micro RNA function. D-elp1 depletion results in increased steady state levels of representative transposon RNAs and a decrease in the corresponding transposon antisense transcripts and endo siRNAs. In D-elp1 null third instar larvae transposon RNA levels are also increased and the corresponding transposon antisense RNAs are reduced | Drosophila melanogaster |

2.7.7.48 | additional information | Drosophila melanogaster | D-elp1, corresponding to the largest of the three subunits in the RNA polymerase II core elongator complex, has RNA-dependent RNA polymerase activity. RdRP activity is associated with the amino terminal 96-kD fragment, DELTAC, CDS 1-2528. D-elp1 is a noncanonical RdRP that can synthesize dsRNA from different ssRNA templates using either a primer-dependent or primer-independent initiation mechanism, overview. D-elp1 associates tightly with Dcr-2 | ? | - |
