Background
- Mobile elements-segments of DNA that are able to "jump" from one adult organism to another.
- 1st discovered by Barbara McClintock and found in ALL organisms
- ~50% of the Human genome is composed of transposable elements
- 3 types of transposons
- Today's focus: DNA-only cut and paste elements
TcBuster and SPINon are highly active in mammalian cells
Mobile DNA Elements
"A resurrected mammalian hAT transposable element and a closely related insect element are highly active in human cell culture"
Purpose: To characterize two hAT elements, Space Invaders (SPIN) and TcBuster.
- hAT is a superfamily of eukaryotic transposable elements
- SPIN and TcBuster are part of a subfamily known as Buster elements
- SPIN- currently inactive, but were once highly active in several vertebrate genomes. A "resurrected" SPIN element (highly active in human cells) was produced and used for this study.
- TcBuster- Currently active . From Tribolium castaneum, a red flour beetle. Also happens to be highly active in human cells.
