Cellular component

Nan1p-containing subcomplex of 90S preribosome

A protein complex that forms a subcomplex of the 90S preribosome and is required for the subsequent assembly of the rest of the preribosome. In S. cerevisiae, it is composed of Utp5p, Utp4p, Nan1p, Utp8p, Utp9p, Utp10 and Utp15p.

Note that the term name uses Saccharomyces gene product names because no other names have yet arisen for this complex; the term nevertheless can be used for analogous complexes in other eukaryotes, and the name can be changed if better wording is found.
