URA3 is often used in yeast research as a "marker gene", that is, a gene to label chromosomes or plasmids. URA3 encodes Orotidine 5'-phosphate decarboxylase (ODCase) , which is an enzyme that catalyzes one reaction in the synthesis of pyrimidine ribonucleotides (a component of RNA ).
In yeast and bacteria, OMP decarboxylase is a single-function enzyme.However, in mammals, OMP decarboxylase is part of a single protein with two catalytic activities.This bifunctional enzyme is named UMP synthase and it also catalyzes the preceding reaction in pyrimidine nucleotide biosynthesis, the transfer of ribose 5-phosphate from 5-phosphoribosyl-1-pyrophosphate to orotate to form OMP.
[2] [3] Many of the targeted alleles are designed so that they can generate both complete and conditional gene knockout mice. [3] [4] The IKMC was initiated on March 15, 2007, at a meeting in Brussels. By 2011, Nature reported that approximately 17,000 different genes have already been disabled by the consortium, "leaving only around 3,000 more ...
The yeast deletion project, formally the Saccharomyces Genome Deletion Project, is a project to create data for a near-complete collection of gene-deletion mutants of the yeast Saccharomyces cerevisiae. Each strain carries a precise deletion of one of the genes in the genome. This allows researchers to determine what each gene does by comparing ...
A conditional gene knockout allows gene deletion in a tissue in a tissue specific manner. This is required in place of a gene knockout if the null mutation would lead to embryonic death, [13] or a specific tissue or cell type is of specific interest. This is done by introducing short sequences called loxP sites around the gene.
Gene knockout in rats is much harder and has only been possible since 2003. [1] [2] The first recorded knockout mouse was created by Mario R. Capecchi, Martin Evans, and Oliver Smithies in 1989, for which they were awarded the 2007 Nobel Prize in Physiology or Medicine.
Gene knock-in originated as a slight modification of the original knockout technique developed by Martin Evans, Oliver Smithies, and Mario Capecchi.Traditionally, knock-in techniques have relied on homologous recombination to drive targeted gene replacement, although other methods using a transposon-mediated system to insert the target gene have been developed.

Conditional gene knockout is a technique used to eliminate a specific gene in a certain tissue, such as the liver. [1] [2] This technique is useful to study the role of individual genes in living organisms. It differs from traditional gene knockout because it targets specific genes at specific times rather than being deleted from beginning of life.
