CC   -!- FUNCTION: Component of the PELP1 complex involved in the nucleolar
CC       steps of 28S rRNA maturation and the subsequent nucleoplasmic transit
CC       of the pre-60S ribosomal subunit (By similarity). Required for
CC       processing ITS2 sequences from rRNA intermediates during 26S rRNA
CC       maturation (By similarity). Required in the soma to promote normal
CC       proliferation and prevent germline tumor formation (By similarity).
CC       {ECO:0000250|UniProtKB:Q22006, ECO:0000250|UniProtKB:Q9BV38}.
CC   -!- SUBUNIT: Component of the PELP1 complex, composed of at least PELP1,
CC       TEX10 and WDR18. The complex interacts with pre-60S ribosome particles.
CC       {ECO:0000250|UniProtKB:Q9BV38}.
CC   -!- SUBCELLULAR LOCATION: Nucleus, nucleolus
CC       {ECO:0000250|UniProtKB:Q9BV38}. Nucleus, nucleoplasm
CC       {ECO:0000250|UniProtKB:Q4VBE8}.
CC   -!- SIMILARITY: Belongs to the WD repeat IPI3/WDR18 family. {ECO:0000305}.
