Two tandemly arrayed short interspersed repetitive element (SINE) sequences were found in medaka (Oryzias latipes). These two SINE sequences, designated SINE1 and SINE2, were flanked by a 180-bp AT-rich region. Both appeared to be derived from transfer RNA. The former exhibited 80% sequence homology to human tRNA(Ala) and the latter exhibited 94% sequence homology to rat tRNA(Ser). SINE1 contained the retroviral U5 region, whereas SINE2 did not. This is the first sequence-level demonstration of the existence of neighboring SINEs in medaka.
