INTEGRASE PROTEIN Meaning and
Definition
-
Integrase protein is a type of enzyme that plays a crucial role in the life cycle of certain viruses, particularly retroviruses and retrotransposons. Retroviruses are a group of RNA viruses that have the unique ability to convert their RNA genome into DNA and integrate it into the host's genome. This process is essential for the virus to replicate and maintain a long-term infection.
Integrase proteins are responsible for catalyzing the integration of the viral DNA into the host cell's DNA. They achieve this by recognizing and binding to specific DNA sequences present in both the viral DNA ends and the host genome. Integrase cleaves the host DNA at these sites and inserts the viral DNA, creating a stable connection between the viral and host genomes.
The integration of viral DNA is a critical step in the life cycle of retroviruses as it ensures the persistence of the viral genetic material within the host cell. It allows the virus to evade the host immune response and establishes a long-term viral reservoir. Additionally, the integrated viral DNA can be transcribed and translated, leading to the synthesis of new viral particles.
Integrase proteins are the target of several antiretroviral drugs used in the treatment and management of retroviral infections, such as HIV. These drugs inhibit the activity of integrase, preventing viral DNA integration and interrupting the viral life cycle. Thus, understanding the structure and function of integrase proteins is fundamental in the development of therapeutic strategies to combat retroviral infections.

Etymology of INTEGRASE PROTEIN
The word "integrase" is derived from the combination of two words: "integrate" and "enzyme".
The term "integrate" originates from the Latin word "integrare", meaning "to make whole or complete". In the context of integrase protein, it refers to the role of this enzyme in integrating foreign DNA or genetic material into the host cell's genome.
The word "enzyme" has its roots in the Greek word "en", meaning "in", and "zyme", meaning "leavened or yeast". It was first coined by the German physiologist Wilhelm Kühne in 1878. Enzymes are proteins that catalyze biological reactions in living organisms, including the process of DNA integration.
