Background La antigen is recognized by antibodies in patients with autoimmune disorders such as systemic lupus erythematosus and Sjögren's syndrome (1). La antigen binds to the 5'-noncoding region of poliovirus RNA and is an IRES trans-acting factor (1,2). Depletion of La antigen reduces the function of poliovirus IRES (3). La antigen, when phosphorylated at Ser366, has been shown to associate with nuclear precursor tRNAs and facilitate their processing (4). The nonphosphorylated La antigen interacts with the mRNAs that have 5'-terminal oligopyrimidine (5'TOP) motifs to control protein synthesis (4).
