dsRNA-gated channel SID-1
This is a family of proteins that are transmembrane dsRNA-gated channels. They passively transport dsRNA into cells and do not act as ATP-dependent pumps. They are required for systemic RNA interference. This family of proteins belong to the CREST superfamily, which are distantly related to GPCRs.
