Protein: Something about silencing protein 10 (U three protein 3) (U3 small nucleolar RNA-associated protein 3) (U3 snoRNA-associated protein 11) (Q12136)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: Primarily required at the G2/M phase. Essential for viability: involved in nucleolar processing of pre-18S ribosomal RNA as part of the ribosomal small subunit (SSU) processome.
Subcellular location: Nucleus, nucleolus {ECO:0000269|PubMed:12068309, ECO:0000269|PubMed:9611201}.
