| Background: | The protein encoded by this gene is involved in diverse aspects of RNA metabolism, including binding and protecting poly(U) termini of nascent RNA polymerase III transcripts from exonuclease digestion, processing 5' and 3' ends of pre-tRNA precursors, acting as an RNA chaperone, and binding viral RNAs associated with hepatitis C virus. Autoantibodies reacting with this protein are found in the sera of patients with Sjogren syndrome and systemic lupus erythematosus. Alternative promoter usage results in two different transcript variants which encode the same protein. |
| UniProt Protein Function: | SSB: a nuclear protein that plays a role in the transcription of RNA polymerase III. It is most probably a transcription termination factor. Binds to the 3' termini of virtually all nascent polymerase III transcripts. It is associated with precursor forms of RNA polymerase III transcripts including tRNA and 4.5S, 5s, 7s, and 7-2 RNAs. |
| UniProt Protein Details: | Protein type:Transcription initiation complex Chromosomal Location of Human Ortholog: 2q31.1 Cellular Component: nuclear chromosome, telomeric region; ribonucleoprotein complex Molecular Function:mRNA binding; nucleotide binding; protein binding; tRNA binding Biological Process: histone mRNA metabolic process; tRNA modification |
