In biology, 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 tends to be very small; on the order of 500–1,000 base pairs. They may exist incorporated into an integron or freely as circular DNA. [1]
An expression cassette is a distinct component of vector DNA consisting of a gene and regulatory sequence to be expressed by a transfected cell. [1] In each successful transformation, the expression cassette directs the cell's machinery to make RNA and protein(s). Some expression cassettes are designed for modular cloning of protein-encoding ...
Cassette mutagenesis via Golden Gate Assembly. Cassette mutagenesis is a type of site-directed mutagenesis that uses a short, double-stranded oligonucleotide sequence (gene cassette) to replace a fragment of target DNA. It uses complementary restriction enzyme digest ends on the target DNA and gene cassette to achieve specificity.
Meta databases are databases of databases that collect data about data to generate new data. They are capable of merging information from different sources and making it available in a new and more convenient form, or with an emphasis on a particular disease or organism.
The NBD or ATP-binding cassette (ABC) domain, on the other hand, is located in the cytoplasm and has a highly conserved sequence. The NBD is the site for ATP binding. [ 23 ] In most exporters, the N-terminal transmembrane domain and the C-terminal ABC domains are fused as a single polypeptide chain, arranged as TMD-NBD-TMD-NBD.
Cassette maintenance requires that they be integrated within a replicative element (chromosome, plasmids). The integrase encoded by the integron preferentially catalyses two types of recombination reaction: 1) attC x attC, which results in cassette excision, 2) attI x attC, which allows integration of the cassette at the attI site of the integron.
Trapping is performed with gene trap vectors whose principal element is a gene trapping cassette consisting of a promoterless reporter gene and/or selectable genetic marker, flanked by an upstream 3' splice site (splice acceptor; SA) and a downstream transcriptional termination sequence (polyadenylation sequence; polyA).
ATP-binding cassette transporter sub-family C member 11, also MRP8 (Multidrug Resistance-Related Protein 8), is a membrane transporter that exports certain molecules from inside a cell. It is a protein that in humans is encoded by gene ABCC11 .
