CC   -!- SUBUNIT: Component of the 40S small ribosomal subunit. Interacts with
CC       sta. {ECO:0000250|UniProtKB:O76927}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC       {ECO:0000250|UniProtKB:P63220}. Cytoplasm
CC       {ECO:0000250|UniProtKB:P63220}. Rough endoplasmic reticulum
CC       {ECO:0000250|UniProtKB:P63221}. Note=Detected on cytosolic polysomes
CC       (By similarity). Detected in ribosomes that are associated with the
CC       rough endoplasmic reticulum (By similarity).
CC       {ECO:0000250|UniProtKB:P63220, ECO:0000250|UniProtKB:P63221}.
CC   -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically. Zygotic
CC       expression is high in middle-stage embryos, lower in middle-stage
CC       larvae, dropping through pupal development to be much lower in adults.
CC       {ECO:0000269|PubMed:15211551}.
CC   -!- SIMILARITY: Belongs to the eukaryotic ribosomal protein eS21 family.
CC       {ECO:0000305}.
