The Beta subunit of cholera toxin binds to a GM1-ganglioside receptor which is widely accepted to initiate toxin action by triggering uptake and delivery of the toxin Alpha subunit into cells. The holotoxin consists of a pentameric ring of Beta subunits whose central pore is occupied by the Alpha subunit. The Alpha subunit contains two chains, A1 and A2, linked by a disulfide bridge. The Alpha subunit (and Cholera toxin) activate the adenylate cyclase enzyme in cells of the intestinal mucosa leading to increased levels of intracellular cAMP.Synonyms: Cholera enterotoxin B chain, Cholera enterotoxin gamma chain, Choleragenoid, VC_1456, ctxB, toxB
