Function

[RL1_THETH] The L1 stalk is quite mobile in the ribosome, and is involved in E site tRNA release (By similarity). Binds directly to 23S rRNA.[HAMAP-Rule:MF_01318] Protein L1 is also a translational repressor protein, it controls the translation of the L11 operon by binding to its mRNA (By similarity).[HAMAP-Rule:MF_01318]

Publication Abstract from PubMed

Ribosomal protein L1 has a dual function as a ribosomal protein binding 23S rRNA and as a translational repressor binding its mRNA. L1 is a two-domain protein with N- and C-termini located in domain I. Earlier it was shown that L1 interacts with the same targets on both rRNA and mRNA mainly through domain I. We have suggested that domain I is necessary and sufficient for specific RNA-binding by L1. To test this hypothesis, a truncation mutant of L1 from Thermus thermophilus, representing domain I, was constructed by deletion of the central part of the L1 sequence, which corresponds to domain II. It was shown that the isolated domain I forms stable complexes with specific fragments of both rRNA and mRNA. The crystal structure of the isolated domain I was determined and compared with the structure of this domain within the intact protein L1. This comparison revealed a close similarity of both structures. Our results confirm our suggestion that in protein L1 its domain I alone is sufficient for specific RNA binding, whereas domain II stabilizes the L1-rRNA complex.

Domain I of ribosomal protein L1 is sufficient for specific RNA binding.,Tishchenko S, Nikonova E, Kljashtorny V, Kostareva O, Nevskaya N, Piendl W, Davydova N, Streltsov V, Garber M, Nikonov S Nucleic Acids Res. 2007;35(21):7389-95. Epub 2007 Oct 25. PMID:17962298^[1]
