PROTOP (DF0001684)

Autonomous DNA transposon; a molecular fossil.


The PROTOP consensus sequence encodes PROTOPp, a 855-aa P-like transposase (positions 1221-3785, just one ORF). PROTOP has perfect 31 bp-long TIRs and its copies are flanked by 7-bp target site duplications generated upon their integration in the genome. All P-like transposases, including PROTOPp (positions 31-89), contain a conserved ~60-aa zinc finger motif (smart00692, DM3) at their N-terminus. The DM3 motif is located downstream of the previously reported zinc finger motif.
