Drosophila protein sequences encoded

All elastic proteins contain distinct domains, of which at least one is made up of elastic repeat sequences, and they all contain cross-links between residues in either the nonelastic or elastic domains [9]. Previously, the Drosophila CGI5920 gene was tentatively identified as one encoding a resUin-like protein [31]. To prepare recombinant resilin, we chose to express the first exon of the Drosophila CG15920 gene [29], which encodes an N-terminal domain in the native protein comprising 17 copies of the putative elastic repeat motif GGRPSDSYGAPGGGN [31]. 

A second Drosophila transposon called mariner630 typifies the mariner / Tel transposon superfamily, which also contains members from nematodes,631 other invertebrates, fishes,632 amphibia,633 and possibly human beings.634 These transposons encode a transposase containing a D, D, D or D, D, E motif630 but no other proteins. They contain short 30-bp terminal inverted repeats and become inserted into host TA sequences.631 Movement of some repetitive sequences of the LINE635 and SINE636 families within the human genome may be assisted by mariner transposons.637...
