Organization of TCAST elements within T Organization of TCAST elements within T. castaneum genome in the form of TCAST transposon-like element, tandem arrays, and CR1-3_TCa retrotransposon. Organization of TCAST elements within T. castaneum genome in the form of TCAST transposon-like element, tandem arrays, and CR1-3_TCa retrotransposon. Regions corresponding to TCAST element are shown in red. TCAST transposon-like element contains an almost complete TCAST monomer and a monomer segment of approximately 121 bp in an inverted orientation, whereas CR1-3 retrotransposon contains segment corresponding to 1.2 monomer. Within TCAST transposon-like element terminal inverted repeats (arrows) unique nonsatellite sequence (green), target-site duplication in the form of “ACT,” and the insertion point of 925-bp sequence found within TR 1.9, element and coding for the putative transposase are shown. Three short ORFs within TCAST transposon-like element are also indicated. Within nonlong terminal repeat retrotransposon CR1-3_TCa regions corresponding to 5′UTR and to two ORFs are indicated.
