rpsJ, 30S ribosomal protein S10
Also Known as
RS10_ECOLI, rpsJ, nusE
Involved in the binding of tRNA to the ribosomes (PubMed:6759118). In addition, in complex with NusB, is involved in the regulation of ribosomal RNA (rRNA) biosynthesis by transcriptional antitermination. S10 binds RNA non-specifically and increases the affinity of NusB for the boxA RNA sequence (PubMed:7678781, PubMed:11884128, PubMed:16109710). S10 may constitute the critical antitermination component of the NusB-S10 complex (PubMed:19111659). Part of the 30S ribosomal subunit (PubMed:10094780, PubMed:12244297, PubMed:12809609, PubMed:16272117, PubMed:27906160, PubMed:27906161, PubMed:27934701, PubMed:28077875, PubMed:7007073). Can also form a heterodimer with the transcription antitermination protein NusB (PubMed:1731086, PubMed:11884128, PubMed:16109710, PubMed:19111659). Binding of S10 to NusB is mutually exclusive with its incorporation into the ribosome (PubMed:19111659).
