EOG8323FM GO:0008270 27/78 zinc ion binding molecular_function "Interacting selectively and non-covalently with zinc (Zn) ions." [GOC:ai] EOG8323FM GO:0005634 2/78 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] EOG8323FM GO:0003676 2/78 nucleic acid binding molecular_function "Interacting selectively and non-covalently with any nucleic acid." [GOC:jl] EOG8323FM GO:0030532 1/78 small nuclear ribonucleoprotein complex cellular_component "A complex composed of RNA of the small nuclear RNA (snRNA) class and protein, found in the nucleus of a eukaryotic cell. These are typically named after the snRNA(s) they contain, e.g. U1 snRNP or U4/U6 snRNP. Many, but not all, of these complexes are involved in splicing of nuclear mRNAs."
