Protein
50S ribosomal protein L1
Organism
Methanococcus vannielii (strain ATCC 35089 / DSM 1224 / JCM 13029 / OCM 148 / SB)
Function
Protein L1 is also a translational repressor protein, it controls the translation of the L1 operon by binding to its mRNA. Thus it also controls transcription of L10 and L12 by translational coupling. Unlike the case in E.coli, where the site is in the untranslated mRNA leader, this site is within the L1 protein's structural gene.
Similarity
Belongs to the universal ribosomal protein uL1 family.
