Any of several heterodimers containing one or two Noc proteins, associated with preribosomal complexes; involved in ribosome biogenesis.
Comment:
Noc complexes exhibit a dynamic intranuclear location; consider also annotating to 'nucleolus ; GO:0005730' and/or 'nucleoplasm ; GO:0005654'. Note that the definition uses Saccharomyces gene product names because this complex has only been described in Saccharomyces cerevisiae and no other names have yet arisen; the term nevertheless can be used for analogous complexes in other eukaryotes, and the definition can be changed if better wording is found.
