CEMUDR1 is an autonomous DNA transposon - a consensus. autonomous DNA transposon; 9-bp TSD; transposase; MUDR superfamily; PAL9A_CE; LONGPAL. CEMUDR1 is an autonomous DNA transposon; there are several copies of CEMUDR1 in the genome; they are ~99% identical 9-bp target sites. CEMUDR1 has 250-bp identical terminal inverted repeats. It caries copies of two different CEREP46B-like. CEMUDR1 encodes CEMUDR1p, a 656-aa MUDR-like transposase. CEMUDR1p is encoded by 9 exons (based on prediction by GeneFinder, dot.imgen.bcm.tmc.edu:9331/gene-finder/gf.html). CDS join(1477..1803,2602..2731,2825..3056,3326..3455, 3782..4043,4120..4257,4684..4879,5177..5461, 5579-5849) There are several CEMUDR1-like families in the genome; PAL9A_CE, LONGPAL1 and LONGPAL2 are nonautonomous elements transposed by CEMUDR1p-like transposases.
CEMUDR2 is an autonomous DNA transposon - a consensus. autonomous DNA transposon; 9-bp TSD; transposase; MUDR superfamily; LONGPAL2. CEMUDR2 is an autonomous DNA transposon; there are two copies of CEMUDR2 in the genome; they are ~98% identical with each other. One of them is flanked by a 9-bp target site duplication. CEMUDR2 has ~450-bp nearly identical terminal inverted repeats. CEMUDR2 encodes CEMUDR2p, a 742-aa MUDR-like transposase. CEMUDR2p is encoded by 15 exons (based on prediction by GeneFinder, dot.imgen.bcm.tmc.edu:9331/gene-finder/gf.html). CEMUDR2 and LONGPAL2 share 92% identical ~500-bp termini. There is a low 62% nucleotide identity between CEMUDR2 and CEMUDR1. Transposases CEMUDR2p and CEMUDR1p are 30% identical to each other. These transposases form the same superfamily together with MuDR-like transposases in plants and ISRm3/IS1201-like transposases in bacteria.
Internal part of retrotransposon CER1; gypsy/Ty3 group. retrotransposon CER1; LTR; gag; pol; env; gypsy/Ty3 group. LTRs of CER1 are named as LTRCER1. CDS 730..7548 (product= gag, pol and env protein precursor) A gypsy/Ty3-class retrotransposon (Cer1) has 492 bp terminal repeats and one long (6819 nt) open reading frame. Alignment with other gypsy-class elements and with retroviruses indicates that an env gene occupies the 3' 1.2 kb of the open reading frame. Since gypsy of Drosophila has been shown to be an infectious element, it is possible that gypsy-like elements are active in C. elegans.
