RL J. Biol. Chem. 286:15391-15402(2011).
CC -!- FUNCTION: Required for both pre-rRNA processing and heterochromatic
CC gene silencing. {ECO:0000269|PubMed:21385875}.
CC -!- FUNCTION: Component of the RIX1 complex required for processing of ITS2
CC sequences from 35S pre-rRNA. {ECO:0000250|UniProtKB:P53877}.
CC -!- SUBUNIT: Component of the RIX1 complex, composed of ipi1, rix1/ipi2 and
CC crb3/ipi3 in a 1:2:2 stoichiometry. The complex interacts (via rix1)
CC with mdn1 (via its hexameric AAA ATPase ring) and the pre-60S ribosome
CC particles (By similarity). Interacts with rix1, gcr3 and Las1
CC (PubMed:21385875). {ECO:0000250|UniProtKB:P53877,
CC ECO:0000269|PubMed:21385875}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:21385875}. Chromosome
CC {ECO:0000269|PubMed:21385875}.
CC -!- SIMILARITY: Belongs to the WD repeat IPI3/WDR18 family. {ECO:0000305}.
