Furthermore, alterations in photoaffinity labeling were observed with the F335A mutants.3° This does not exclude the fact that other regions in P-glycoprotein play a functional role in drug binding or transport. Login to comment

In particular, point mutations in G185V in human P-glycoprotein (immediately before TM3)31 and $941F or $939F in TMll of mouse P-glycoprotein encoded by rndrl and mdr3, respectively, altered drug resistance profiles32and the ability to photolabel the mutant proteins.33'34In summary, these data suggest that different drugs have overlapping but distinct binding sites, and some of the drug-binding sites may exist outside the photolabeling regions.
