Short Interspersed Elements (SINEs) are mobile genetic elements of higher eukaryotes, which originated during evolution from various tRNAs and less often from 5S rRNA and 7SL RNA. Similar to the genes of these RNAs, SINEs are transcribed by RNA polymerase III. The transcripts of some mammalian SINEs have an ability to undergo AAUAAA-dependent polyadenylation, which is unique for the RNA polymerase III transcripts. It is well known that this polyadenylation of many RNA polymerase II transcripts (e.g., mRNAs) increases their lifetim
