disease:Sera from patients with systemic lupus erythematosus (SLE) often contain antibodies that react with the normal cellular La protein as if this antigen was foreign. ,function:La protein 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. ,PTM:Phosphorylated. The phosphorylation sites are at the C-terminal part of the protein. ,PTM:The N-terminus is blocked. ,similarity:Contains 1 HTH La-type RNA-binding domain. ,similarity:Contains 1 RRM (RNA recognition motif) domain. ,subunit:Interacts with DDX15. May interact with RUFY1. ,
