CC -!- FUNCTION: Required for the processing of the 20S rRNA-precursor to
CC mature 18S rRNA in a late step of the maturation of 40S ribosomal
CC subunits. Has a physiological role leading to 18S rRNA stability (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the small ribosomal subunit. Mature ribosomes
CC consist of a small (40S) and a large (60S) subunit. The 40S subunit
CC contains about 33 different proteins and 1 molecule of RNA (18S). The
CC 60S subunit contains about 49 different proteins and 3 molecules of RNA
CC (25S, 5.8S and 5S).
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the eukaryotic ribosomal protein eS21 family.
CC {ECO:0000305}.
