Cftr - English Definition & Meaning

Definition

CFTR stands for Cystic Fibrosis Transmembrane Conductance Regulator. It's a gene that provides instructions for making a protein that controls the movement of salt and water in and out of cells. Think of it as a gatekeeper for cell hydration. Mutations in the CFTR gene can cause cystic fibrosis (CF), a genetic disorder affecting the lungs, pancreas, and other organs. The CFTR protein acts as a channel, allowing chloride ions to cross cell membranes. When the CFTR protein is defective, mucus becomes thick and sticky. This clogs the airways and digestive system, leading to various health problems. Understanding the CFTR gene is crucial for developing treatments for CF.

Etymology

The name CFTR is an abbreviation derived from its function: Cystic Fibrosis Transmembrane Conductance Regulator. 'Cystic Fibrosis' refers to the disease caused by mutations in the gene. 'Transmembrane' indicates that the protein spans the cell membrane. 'Conductance Regulator' means it controls the flow of ions across the membrane. The CFTR gene was identified in 1989 by researchers studying cystic fibrosis. Its discovery was a major breakthrough in understanding and treating the disease.
