Cellular component

A protein complex that forms a subcomplex of the 90S preribosome. In S. cerevisiae, it is composed of Mpp10p, Imp3p and Imp4p.

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.
