Folding of influenza hemagglutinin in the endoplasmic reticulum.
1 Aug 1991
Abstract excerpt
The folding of influenza hemagglutinin (HA0) in the ER was analyzed in tissue culture cells by following the formation of intrachain disulfides after short (1 min) radioactive pulses. While some disulfide bonds were already formed on the nascent chains, the subunits acquired their final disulfide composition and antigenic epitopes posttranslationally. Two posttranslational folding intermediates were identified....
