WebCFTR. trafficking defect. Mutations cause abnormal post-translational processing and folding of the CFTR protein, preventing correct trafficking to the cell surface. Defective. channel regulation. Often called “gating mutations”—CFTR protein is made and reaches the cell surface, but the channel is rarely open. WebRegulation of CFTR Trafficking by USP10. CFTR is a member of the ABC transporter superfamily and is responsible for chloride homeostasis across the cell membrane in epithelial cells. The surface expression of CFTR is tightly controlled by recycling in endosomes, where the ubiquitination of CFTR targets it to the lysosome for degradation.
WebThese results indicate that, in human nasal cells, VIP rescues trafficking and membrane insertion of functional F508del-CFTR channels at physiological temperature by stimulating both PKA- and PKC-dependent pathways.
