Abstract:
ATMU9 is a fossil of a relatively ancient autonomous DNA transposon that belongs to the MuDR superfamily. There are only two copies of ATMU9 in the genome (chromosomes 2 and 3; they are 87% identical to each other. ATMU9 is flanked by 90% identical ~240-bp TIRs. ATMU9 represents one of tens MuDR-like families present today in the A. thaliana genome. It is flanked by a 10-bp target site duplication. Exons that encode the ATMU9 transposase (~ positions 780-3600) are damaged by several mutations accumulated in the ATMU9 copy since its insertion into the genome. A short ~150-aa protein is encoded by the second strand (positions 4350-3819). The protein is conserved in different ATMU families; we classify it as a DNA-binding protein.
