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}.
