CC   -!- FUNCTION: Binds directly to 23S rRNA. The L1 stalk is quite mobile in
CC       the ribosome, and is involved in E site tRNA release.
CC       {ECO:0000255|HAMAP-Rule:MF_01318}.
CC   -!- FUNCTION: Protein L1 is also a translational repressor protein, it
CC       controls the translation of the L11 operon by binding to its mRNA.
CC       {ECO:0000255|HAMAP-Rule:MF_01318}.
CC   -!- SUBUNIT: Part of the 50S ribosomal subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01318}.
CC   -!- SIMILARITY: Belongs to the universal ribosomal protein uL1 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01318}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABM79508.1; Type=Erroneous initiation; Evidence={ECO:0000305};
