Later, this element was also described in ''Drosophila melanogaster'' as a LTR retrotransposon combining structural features of DNA viruses, retroviruses and non-viral transposable elements ([[Literature:41632|Lankenau et al. 1988]]). ''Micropia'' belongs to ''Micropia/mdg3'' clade ([[Literature:46552|Malik and Eickbush 1999]]).<br /> <br /> ''Micropia'' has several subtypes, the clone Dm11 of ''D. melanogaster'' is taken as a representative. The genomic structure of this clone is 5.5 Kb in size including LTRs of 480 nt. The internal region displays a Primer Binding Site (PBS) complementary to a tRNA&lt;sup&gt;Leu&lt;/sup&gt;, a single Open Reading Frame (ORF), which codifies for a gag-pol polyprotein, and a Polypurine Tract (PPT) adjacent to the 3&amp;acute;LTRs. ''Micropia'' also has a region of similarity to the class I major histocompatibility complex of mammals ([[Literature:41632|Lankenau et al. 1988]]). This element also encodes an antisense RNA complementary to the Reverse Transcriptase_RNaseH region that seems to be involved in the control expression of transposon-encoded proteins in germ lines ([[Literature:41633|Lankenau, Corces and Lankenau 1994]]).<br /> |structure=Micropia.png<br /> |host=Drosophila melanogaster<br /> |hostpic=Drosophila_melanogaster.gif<br /> |literature=*[[Literature:15303|Mobile DNA II.
