CC -!- FUNCTION: Binds the lower part of the 30S subunit head. Binds mRNA in
CC the 70S ribosome, positioning it for translation (By similarity).
CC {ECO:0000250}.
CC -!- FUNCTION: Plays a role in mRNA unwinding by the ribosome, possibly by
CC forming part of a processivity clamp. {ECO:0000269|PubMed:15652481}.
CC -!- SUBUNIT: Part of the 30S ribosomal subunit (PubMed:387449,
CC PubMed:7556101, PubMed:12809609, PubMed:16272117, PubMed:27934701,
CC PubMed:10094780, PubMed:12244297, PubMed:27906160, PubMed:27906161,
CC PubMed:28077875). Forms a tight complex with proteins S10 and S14 (By
CC similarity). With proteins S4 and S5 encircles the mRNA as it enters
CC the ribosome, which may play a role in mRNA helicase processivity. Some
CC nascent polypeptide chains are able to cross-link to this protein in
CC situ. {ECO:0000255|HAMAP-Rule:MF_01309, ECO:0000269|PubMed:10094780,

CC -!- MASS SPECTROMETRY: Mass=25851.9; Method=MALDI;
CC Evidence={ECO:0000269|PubMed:10094780};
CC -!- SIMILARITY: Belongs to the universal ribosomal protein uS3 family.
CC {ECO:0000305}.
