... endocytosis in the proximal tubule is regulated by protein complexes containing a number of transmembrane and accessory proteins including PDZ scaffolds such as NHERF1 and NHERF2. PDZ scaffold proteins bind to class I PDZ binding motifs (S/T-X-Φ) in the extreme C-terminus of targets. Megalin contains...

...Sang-Ho Kwon; Harvey Pollard; William B. Guggino ΔF508 CFTR can be functionally restored in the plasma membrane by exposure of the cell to lower temperature. However, restored ΔF508 CFTR has a much shorter half-life than normal. We studied whether NHERF1, which binds to the PDZ motif of CFTR, might...
