REV PROTEIN Meaning and
Definition
-
Rev protein is a regulatory protein encoded by the rev gene. It is an essential component of the Human Immunodeficiency Virus (HIV) and plays a crucial role in the viral replication process. The primary function of the rev protein is to facilitate the export of unspliced or partially spliced viral mRNA from the nucleus to the cytoplasm of the host cell, thereby allowing the translation of these mRNA molecules into viral proteins.
Rev protein is an RNA-binding protein that recognizes a specific RNA sequence known as the Rev response element (RRE) within the viral mRNA. It interacts with the cellular export machinery and forms a complex with the RRE region, leading to the nuclear export of the viral RNA. This process is necessary for efficient viral replication as it ensures the production of viral proteins required for the assembly and maturation of new viral particles.
The rev protein also functions as a post-transcriptional regulator by enhancing the processing and stability of viral mRNA. It interacts with various host cellular factors to modulate the splicing and nuclear retention of these RNA molecules. Through its multifunctional roles, the rev protein is involved in regulating the expression of viral genes and facilitating the evasion of host immune responses by HIV.
Overall, rev protein is a critical component of HIV replication, as it is responsible for transporting viral mRNA out of the nucleus and promoting the translation of viral proteins. Understanding the mechanisms and functions of rev protein can provide valuable insights into the development of antiviral strategies and therapeutic interventions against HIV infection.

Etymology of REV PROTEIN
The etymology of the word "rev protein" is as follows:
The term "rev" is derived from the word "regulator of expression of virion gene". It was first used to describe a regulatory protein found in the Human Immunodeficiency Virus (HIV). This protein, encoded by the rev gene, is responsible for the export of unspliced viral RNA from the nucleus to the cytoplasm of infected cells.
The usage of "rev" to describe this protein likely originated from the need to find a concise and memorable name for this specific regulatory protein. By combining the words "regulator" and "expression of virion gene", the term "rev" was created.
Over time, the term "rev" has become widely accepted and used to describe similar regulatory proteins found in other retroviruses. The usage of "rev protein" has expanded to include a broader category of viral regulatory proteins involved in gene expression.
