A gene cassette is a type of mobile genetic element that contains a gene and a recombination site. Each cassette usually contains a single gene and tend to be very small; on the order of 500–1000 base pairs. They may exist incorporated into an integron or freely as circular DNA. Gene cassettes can move around within an organism's genome or be transferred to another organism in the environment via horizontal gene transfer. These cassettes often carry antibiotic resistance genes. An example would be the kanMX cassette which confers kanamycin (an antibiotic) resistance upon bacteria.

Process for producing physiologically active protein using genetically modified silkworm
InactiveUS20050177877A1Improve purification effectEasy to aimAnimal cellsDepsipeptidesProtein targetActive protein
The present invention provides a genetic engineering material for insects that enables a target protein to be purified easily, without requiring the use of recombinant baculovirus, while simultaneously providing a process for producing exogenous protein using that genetic engineering material. A gene recombinant silkworm is obtained by inserting an exogenous protein gene such as a cytokine gene coupled to a promoter that functions in silk glands into a silkworm chromosome. An exogenous protein such as a cytokine is then extracted and purified from the silk glands or cocoon of that silkworm or its offspring. A large amount of exogenous protein can be produced within silk gland cells, outside silk gland cells or in silk thread or a cocoon by inserting an expression gene cassette, in which the DNA sequence of the 3′ terminal portion and the DNA sequence of the 5′ terminal portion of fibroin H chain gene are fused to the exogenous protein gene, into silk gland cells and so forth.
