The TetR protein primarily functions as a transcriptional repressor regulating tetracycline resistance genes, especially those that encode efflux pumps like TetA. Its main functions are:Regulation of Efflux Genes: TetR binds to the operator region of...

Chemical genetics refers to the modification of biological macromolecules to interact with previously unrecognized small molecules, thereby achieving controlled and reversible (initiating or interrupting specific reactions with the addition or remova...

When studying gene function, a common approach is to reduce or block gene expression and then analyze the phenotype. For over a decade, RNA interference (RNAi) has been the king in this field. However, the emergence of new technologies, especially C...

A transposon, also known as a transposable element or jumping gene, is a DNA sequence that can change its position within the genome. Sometimes, it creates or reverses mutations that alter the genetic characteristics of cells and the size of the gen...

The RNA polymerase Pol III uniquely transcribes small noncoding RNAs, including 5S rRNAs (type 1), tRNAs (type 2), and a number of other small RNAs (type 3), such as U6 snRNA. Pol III promoters can be divided into three types: type 1 and type 2 and ...

Based on their structure, detergents can be broadly classified as: Ionic, Zwitterionic and Non-ionic. Ionic detergents contain anionic or cationic head groups and possess a net charge. The size of an ionic detergent micelle is determined by the comb...

SUMO Protease, also known as Ulp, is a recombinant fragment of ULP1 (Ubl-specific protease 1) from Saccharomyces cerevisiae. It is highly specific for the SUMO protein fusion, recognizing the tertiary structure of SUMO rather than an amino acid. The...

Adeno-associated virus (AAV) is a replication-defective single-stranded DNA virus of the Parvoviridae family. Productive infection of AAV requires the presence of a helper virus, such as adenovirus (Ad) or herpes simplex virus(HSV). AAV has a genome...
