Two Tandemly Arrayed Transfer-RNA-Derived SINEs of the Medaka (Oryzias latipes)

Two Tandemly Arrayed Transfer-RNA-Derived SINEs of the Medaka (Oryzias latipes)

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...

Zusammenfassung: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.
