Fusion gene

From Wikipedia, the free encyclopedia

A fusion gene is a hybrid gene formed from two previously separate genes. It can occur as the result of a translocation, interstitial deletion, or chromosomal inversion. The fusion of two genes is often taken as evidence that these genes have related functions[1]. Often, fusion genes are oncogenes; examples include BCR-ABL, FIG-ROS, and TEL-JAK2.

Biologists may also deliberately create fusion genes for research purposes. For example, by creating a fusion gene of a protein of interest and green fluorescent protein, the protein of interest may be observed in cells or tissue using fluorescence microscopy. The protein synthesized when a fusion gene is expressed is called a fusion protein.
