[https://www.uniprot.org/uniprot/DRB1_ARATH DRB1_ARATH] Double-stranded RNA-binding protein involved in RNA-mediated post-transcriptional gene silencing (PTGS). Functions in the microRNAs (miRNAs) biogenesis by assisting DICER-LIKE 1 (DCL1) in the accurate processing from primary miRNAs (pri-miRNAs) to miRNAs in the nucleus. Forms a complex with SERRATE (SE) and DCL1 to promote accurate processing of pri-miRNAs by DCL1. Binds and assist DCL1 for accurate processing of precursor miRNAs (pre-miRNA). Indirectly involved in the production of trans-acting small interfering RNAs (ta-siRNAs) derived from the TAS1, TAS2 or TAS3 endogenous transcripts by participating in the production of their initiating miRNAs. Involved with argonaute 1 (AGO1) in the guide strand selection from miRNA duplexes, presumably by directional loading of the miRNA duplex (guide stand and passenger strand) onto the RNA-induced silencing complex (RISC) for passenger strand degradation. Does not participate in sense transgene-induced post-transcriptional gene silencing (S-PTGS). Involved in several plant development aspects and response to hormones through its role in miRNAs processing.<ref>PMID:11148283</ref> <ref>PMID:14722360</ref> <ref>PMID:14972688</ref> <ref>PMID:15821876</ref> <ref>PMID:16428603</ref> <ref>PMID:16889646</ref> <ref>PMID:17337628</ref> <ref>PMID:18632569</ref> <ref>PMID:19304749</ref> <ref>PMID:19861421</ref> <ref>PMID:20462493</ref> <ref>PMID:20735118</ref> | |||
