SID-1 is a dsRNA-selective dsRNA-gated channel.
Systemic RNAi in Caenorhabditis elegans requires the widely conserved transmembrane protein SID-1 to transport RNAi silencing signals between cells. When expressed in Drosophila S2 cells, C. elegans SID-1 enables passive dsRNA uptake from the culture medium, suggesting that SID-1 functions as a channel for the transport of double-stranded RNA (dsRNA). Here we show that nucleic acid transport by...
متن کاملThe SID-1 double-stranded RNA transporter is not selective for dsRNA length.
The double-stranded RNA (dsRNA) transport protein SID-1 enables systemic RNA interference (RNAi) in Caenorhabditis elegans, whereby silencing initiated by local exposure to dsRNA spreads throughout the animal and to its progeny. Previously, we showed that providing dsRNA in the growth medium of Drosophila S2 cells that express C. elegans SID-1 efficiently triggers RNAi. In these experiments lon...
متن کاملSID-1 domains important for dsRNA import in C. elegans
In the nematode Caenorhabditis elegans, RNA interference (RNAi) triggered by doublestranded RNA (dsRNA) spreads systemically to cause gene silencing throughout the organism and its progeny. We confirm that Caenorhabditis nematode SID-1 orthologs have dsRNA transport activity and demonstrate that the SID-1 paralog CHUP-1 does not transport dsRNA. Sequence comparison of these similar proteins, in...

متن کاملTransport of dsRNA into cells by the transmembrane protein SID-1.
RNA interference (RNAi) spreads systemically in plants and nematodes to silence gene expression distant from the site of initiation. We previously identified a gene, sid-1, essential for systemic but not cell-autonomous RNAi in Caenorhabditis elegans. Here, we demonstrate that SID-1 is a multispan transmembrane protein that sensitizes Drosophila cells to soaking RNAi with a potency that is depe...
