CC   -!- FUNCTION: Required for 40S ribosome biogenesis. Involved in nucleolar
CC       processing of pre-18S ribosomal RNA and ribosome assembly. Essential
CC       for vegetative growth (By similarity). {ECO:0000250|UniProtKB:P25586}.
CC   -!- SUBUNIT: Component of the ribosomal small subunit (SSU) processome
CC       composed of at least 40 protein subunits and snoRNA U3. Interacts with
CC       snoRNA U3. Interacts with MPP10, KRI1 and with ribosomal proteins
CC       RPS1A, RPS4A, RPS4B, RPS8A, RPS8B, RPS11A, RPS11B, RPS13, RPS24, RPS25,
CC       RPL4A, RPL7B, RPL8, RPL23, RPL25 and RPL28 (By similarity).
CC       {ECO:0000250|UniProtKB:P25586}.
CC   -!- SUBCELLULAR LOCATION: Nucleus, nucleolus
CC       {ECO:0000250|UniProtKB:P25586}.
CC   -!- SIMILARITY: Belongs to the KRR1 family. {ECO:0000255}.
