Asymmetric Unit(hide GO term definitions)
Chain A,C   (G5ECF1_CAEEL | G5ECF1)
molecular function
    GO:0017151    DEAD/H-box RNA helicase binding    Interacting selectively and non-covalently with the enzyme DEAD/H-box RNA helicase.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0051721    protein phosphatase 2A binding    Interacting selectively and non-covalently with the enzyme protein phosphatase 2A.
    GO:0004540    ribonuclease activity    Catalysis of the hydrolysis of phosphodiester bonds in chains of RNA.
biological process
    GO:0016246    RNA interference    The process in which double-stranded RNAs silence cognate genes. Involves posttranscriptional gene inactivation ('silencing') both of transgenes or dsRNA introduced into a germline, and of the host gene(s) homologous to the transgenes or dsRNA. This silencing is triggered by the introduction of transgenes or double-stranded RNA (dsRNA), and can occur through a specific decrease in the level of mRNA, or by negative regulation of translation, of both host genes and transgenes.
    GO:0090501    RNA phosphodiester bond hydrolysis    The RNA metabolic process in which the phosphodiester bonds between ribonucleotides are cleaved by hydrolysis.
    GO:0030538    embryonic genitalia morphogenesis    The process, occurring in the embryo, by which the anatomical structures of the genitalia are generated and organized.
    GO:0034660    ncRNA metabolic process    The chemical reactions and pathways involving non-coding RNA transcripts (ncRNAs).
    GO:0000184    nuclear-transcribed mRNA catabolic process, nonsense-mediated decay    The nonsense-mediated decay pathway for nuclear-transcribed mRNAs degrades mRNAs in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into truncated, and potentially harmful, proteins.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
