The B subunit pentameric ring directs the A subunit to its target by binding to the GM1 gangliosides present on the surface of the intestinal epithelial cells. It can bind five GM1 gangliosides. It has no toxic activity by itself.

Cholera toxin also known as cholera enterotoxin is a protein complex secreted by the bacterium Vibrio cholerae. This toxin is composed of two subunits A and B where the B subunit facilitates the attachment of the toxin to the intestinal epithelial cells and the A subunit contains the enzymatic activity. Cholera toxin has a molecular mass of approximately 84 kDa. It is expressed by the bacteria within the human small intestine where it invades the intestinal mucosa and exerts its toxic effects.
This toxin disrupts normal cellular processes by modifying the regulatory G protein involved in cellular signaling. Cholera toxin is part of a multi-protein complex that leads to continuous activation of adenylate cyclase. The enhanced activity of adenylate cyclase results in the overproduction of cyclic AMP (cAMP) in intestinal cells. This accumulation of cAMP causes a cascade of events leading to the secretion of chloride ions and water into the intestines producing severe diarrheal symptoms.
Cholera toxin plays a critical role in the cAMP-dependent pathway. Its influence on G proteins specifically the stimulatory Gs alpha subunit results in persistent activation of adenylate cyclase. Related proteins in this pathway include CFTR a chloride channel that becomes overactive due to the elevated cAMP levels. This pathway is important for understanding how electrolyte imbalances occur during cholera infection affecting ion transport and water absorption.
Cholera toxin is intrinsically linked to the disease cholera characterized by acute diarrhea and severe dehydration. The toxin's interaction with the CFTR protein in the small intestine leads to symptoms associated with cholera. In addition research suggests potential roles in gastrointestinal disorders that involve dysregulation of electrolyte balance but these need further investigation. Anti-cholera antibodies and cholera antibodies provide immune protection by neutralizing the toxin's effects forming the basis for therapeutic treatments and vaccination strategies against cholera.
