Term Detail
GO term:small nucleolar ribonucleoprotein complex
Synonym: small nucleolar ribonucleoprotein
Synonym: snoRNP
GO id:GO:0005732
Definition:A ribonucleoprotein complex that contains an RNA molecule of the small nucleolar RNA (snoRNA) family and associated proteins. Most are involved in a step of processing of rRNA: cleavage, 2'-O-methylation, or pseudouridylation. The majority, though not all, fall into one of two classes, box C/D type or box H/ACA type.
CommentsNote that 'nucleolar' in the term name is part of the RNA family designation 'small nucleolar', and does not necessarily reflect the location of the complex.
Number of paths to term: 5

is-adenotes an 'is-a' relationship
part-ofdenotes a 'part-of' relationship
regulatesdenotes a 'regulates' relationship
positively-regulatesdenotes a 'positively-regulates' relationship
negatively-regulatesdenotes a 'negatively-regulates' relationship
