CC   -!- FUNCTION: Required for the assembly and/or stability of the 40S
CC       ribosomal subunit. Required for the processing of the 20S rRNA-
CC       precursor to mature 18S rRNA in a late step of the maturation of 40S
CC       ribosomal subunits. {ECO:0000255|HAMAP-Rule:MF_03015}.
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). Interacts with ribosomal protein S21.
CC       {ECO:0000255|HAMAP-Rule:MF_03015}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03015}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uS2 family.
CC       {ECO:0000255|HAMAP-Rule:MF_03015}.
