Background: La was first found to bind autoantibodies from individuals with Sjogren's syndrome and systemic lupus erythematosus (SLE). La is a transcription factor for RNA polymerase III (Pol III). It participates in the termination of Pol III-mediated transcription and the recycling of the transcriptional machinery. La associates with the 3' oligo U portion of transcripts generated by Pol III. In some cases, this association protects the message from 3' processing. The association of La and mRNA is mediated by the presence of an N-terminal ribonucleoprotein (RNP) consensus sequence in La. The La protein also binds several small RNAs, such as 7S RNA, 5S RNA, and tRNA, and is thought to be involved in their biogenesis. It is known that histone mRNA is stabilized throughout S Phase and is degraded only at the end of S phase. La protein participates in the stabilization of histone mRNA which results in increased production of histone protein. These data suggest that a major function of La is to protect vital nascent transcripts from premature degradation.
