Membranes Flashcards
Cystic fibrosis transmembrane-conductance regulator
CFTR involved in Cl- exit and secretion
Majority of CFbcases caused by mutation leading to deletion of single Phe amino acid –> protein misfolds and fails to traffic to the apical membrane
PGlycoprotein
Genetic variation in expression of PGlycoprotein –> drug efficacy
Gene profiling of patients allows tailoring of drug prescribing
Heart failure
Disturbed protein localisation. Organisation of proteins is tightly controlled, almost crystalline, in heart failure there is no regular array of calcium channels despite the channels being present, lack of arrangement –> no communication. No mutation in calcium channel yet tightly associated with disease –> mutation in scaffolding protein
