CC   -!- FUNCTION: Involved in the small subunit (SSU) processome assembly and
CC       function, and in the 18S rRNA synthesis. Required for the early
CC       cleavages at sites A0, A1 and A2 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus, nucleolus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ESF2/ABP1 family. {ECO:0000305}.
