| GO term | GO name | GO namespace | GO def |
| GO:0003723 | RNA binding | molecular_function | Binding to an RNA molecule or a portion thereof. [GOC:jl, GOC:mah] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0008171 | O-methyltransferase activity | molecular_function | Catalysis of the transfer of a methyl group to the oxygen atom of an acceptor molecule. [GOC:ai] |
| GO:0008173 | RNA methyltransferase activity | molecular_function | Catalysis of the transfer of a methyl group from a donor to a nucleoside residue in an RNA molecule. [GOC:mah] |
| GO:0046872 | metal ion binding | molecular_function | Binding to a metal ion. [GOC:ai] |
| GO:0090486 | small RNA 2'-O-methyltransferase activity | molecular_function | Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to the oxygen atom of a nucleoside residue in a small RNA molecule. Reaction |
| GO:0001510 | RNA methylation | biological_process | Posttranscriptional addition of a methyl group to either a nucleotide or 2'-O ribose in a polyribonucleotide. Usually uses S-adenosylmethionine as a cofactor. [GOC:hjd, PMID:21823225] |
| GO:0034587 | piRNA processing | biological_process | A process leading to the generation of a functional piRNA. piRNAs (Piwi-associated RNAs) are a class of 24- to 30-nucleotide RNAs derived from repeat or complex DNA sequence elements and processed by a Dicer-independent mechanism. [GOC:kmv, PMID:23329111, PMID:24696457, PMID:34724117] |
| GO:0043186 | P granule | cellular_component | A small cytoplasmic, non-membranous RNA/protein complex aggregate in the primordial germ cells of many higher eukaryotes. [GOC:dph, GOC:kmv, PMID:11262230] |
| GO:0005634 | nucleus | cellular_component | 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. [GOC:go_curators] |
| GO:0030422 | siRNA processing | biological_process | A process leading to the generation of a functional small interfering RNA (siRNA). Includes the cleavage of double-stranded RNA to form small interfering RNA molecules (siRNAs) of 21-23 nucleotides. May also include amplification of the siRNA by RNA-directed RNA polymerase. [GOC:mah, PMID:11524674, PMID:19239886, PMID:20687832] |
| GO:0005737 | cytoplasm | cellular_component | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684] |
