FunFam 3: Endoribonuclease dcr-1

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

The RISC complex is involved in posttranscriptional repression of gene expression through downregulation of translation or induction of mRNA degradation.
1 Q9VCU9 (/IDA)
RISC-loading complex GO:0070578
A trimeric protein complex required for the formation of a mature RNA-induced silencing complex (RISC). In humans the complex is composed of the endonuclease Dicer (DICER1), TRBP (TARBP2) and the Argonaute protein Ago2 (EIF2C2/AGO2). Within the complex, Dicer and TRBP are required to process precursor miRNAs (pre-miRNAs) to mature miRNAs and then load them onto Ago2. Ago2 bound to the mature miRNA constitutes the minimal RISC and may subsequently dissociate from Dicer and TRBP. This complex has endoribonuclease activity.
