... cycle. To study this question, we compared the effects of P i analogues (V i ,BeF x ,AlF 4 ), trapping nucleotides at the catalytic site of Pgp, and of ATP depletion, on UIC2- shift and UIC2/MM12.10 ... applied as an indicator of the expression of functional Pgp molecules in clinical tissue samples [20]. Changes in the proteolysis profile of Pgp were also detected in the presence of nucleotides alone ... implication of this finding is that the often variable functional modulation of Pgp by modulators (e.g. CsA) in the UIC2-shift assay can be substituted by the consecutive application of UIC2 and...
