TRANSPORTER REVERSAL Meaning and
Definition
-
Transporter reversal refers to a phenomenon in the field of biochemistry and pharmacology where the function and activity of a cellular transporter protein are altered in a manner opposite to its normal physiological role. Transporters are membrane proteins that facilitate the movement of various molecules across biological membranes, such as the plasma membrane or the membrane of intracellular organelles.
In the case of transporter reversal, the transporter protein, which usually transports specific molecules from one side of the membrane to the other, changes its function and starts to move the transported molecules back in the opposite direction. This alteration in the transporter's activity can occur due to various factors, including genetic mutations, alterations in the cellular environment, or the presence of drugs or other compounds that interact with the transporter.
Transporter reversal can have profound effects on cellular physiology, as it can disrupt the normal balance of molecules within the cell or between different cellular compartments. This alteration in transport can impact various processes, such as the uptake of nutrients, elimination of waste products, or the distribution of signaling molecules within the cell.
Understanding transporter reversal is crucial for the development of pharmacological interventions. Drugs that can selectively modulate transporter activity in a specific direction can be used to alter the transport of certain molecules, thereby influencing cellular processes and potentially providing therapeutic benefits. Furthermore, knowledge of transporter reversal can also help in predicting and understanding drug-drug interactions or adverse side effects that may arise due to the altered transportation of drugs across cellular membranes.
Etymology of TRANSPORTER REVERSAL
The term "transporter reversal" does not have a well-established etymology as it appears to be a specific phrase used in a particular context. However, we can break down the etymology of the individual words involved:
1. Transporter: The word "transporter" comes from the Latin root word "transportare", which means "to carry across". It is derived from the combination of two Latin terms: "trans", meaning "across", and "portare", meaning "to carry".
2. Reversal: The term "reversal" originates from the Latin word "reversus", which is the past participle of "revertere", meaning "to turn back". It combines the prefix "re-", indicating "back" or "again", with "vertere", meaning "to turn".
