CC -!- FUNCTION: Component of the chloroplast ribosome (chloro-ribosome), a
CC dedicated translation machinery responsible for the synthesis of
CC chloroplast genome-encoded proteins, including proteins of the
CC transcription and translation machinery and components of the
CC photosynthetic apparatus. {ECO:0000305|PubMed:10874039,
CC ECO:0000305|PubMed:28007896}.
CC -!- SUBUNIT: Component of the chloroplast small ribosomal subunit (SSU).
CC Mature 70S chloroplast ribosomes of higher plants consist of a small
CC (30S) and a large (50S) subunit. The 30S small subunit contains 1
CC molecule of ribosomal RNA (16S rRNA) and 24 different proteins. The 50S
CC large subunit contains 3 rRNA molecules (23S, 5S and 4.5S rRNA) and 33
CC different proteins. {ECO:0000269|PubMed:10874039,
CC ECO:0000269|PubMed:28007896}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast
CC {ECO:0000269|PubMed:10874039, ECO:0000269|PubMed:28007896}.
CC -!- MASS SPECTROMETRY: Mass=13786; Method=Electrospray;
CC Evidence={ECO:0000269|PubMed:10874039};
CC -!- MASS SPECTROMETRY: Mass=13779; Method=MALDI;
CC Evidence={ECO:0000269|PubMed:10874039};
CC -!- MISCELLANEOUS: Exons 2 and 3 are cis-spliced, while a trans-splicing
CC reaction is required to link exons 1 and 2.
CC -!- SIMILARITY: Belongs to the universal ribosomal protein uS12 family.
CC {ECO:0000305}.
