WebMar 23, 2024 · The protein needs to fold correctly in order to be transported to the cell surface. If it folds incorrectly, it’s not stable and gets degraded before it reaches the surface. The most common type of CF-causing CFTR mutation, F508del, affects the protein’s folding in this way. WebNov 15, 2011 · Most patients with CF carry the F508del CFTR mutation, which causes defective CFTR protein folding and processing in the endoplasmic reticulum, resulting in minimal amounts of CFTR at the cell surface. One strategy to treat these patients is to correct the processing of F508del-CFTR with small molecules. shiny oily faceWebVAR_000171: 508: missing: in CF and CBAVD; most common mutation in Caucasian CF chromosomes; impairs protein folding and stability; causes local changes to the surface that mediates interactions between domains; decreases frequency of channel opening in vitro; binds to the cytokeratin-8 and through this binding is primed for the degradation … shiny old

"WebMost mutations in CF patients result in rapid intracellular degradation of the CFTR protein. While this defect is thought to result from abnormal protein folding, it is unclear how mutant and wild-type (WT) proteins differ in structure, how the cell is able to distinguish these differences, and how the fate of the mutant protein is determined.
