CC   -!- FUNCTION: Component of the 60-80S U3 small nucleolar ribonucleoprotein
CC       (U3 snoRNP). Required for the early cleavages during pre-18S ribosomal
CC       RNA processing (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of a heterotrimeric complex containing IMP3, IMP4
CC       and MPHOSPH10. Interacts with MPHOSPH10 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus, nucleolus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uS4 family.
CC       {ECO:0000305}.
