Ethylmaleimide 0-16 ATP binding cassette subfamily B member 1 Homo sapiens 27-41 9066677-3 1997 In this report, we have examined the effects of N-ethylmaleimide, a potent inhibitor of the P-gp ATPase, on P-gp drug binding in intact MDR cells and in plasma membranes. Ethylmaleimide 48-64 ATP binding cassette subfamily B member 1 Homo sapiens 92-96 9066677-3 1997 In this report, we have examined the effects of N-ethylmaleimide, a potent inhibitor of the P-gp ATPase, on P-gp drug binding in intact MDR cells and in plasma membranes. Ethylmaleimide 48-64 ATP binding cassette subfamily B member 1 Homo sapiens 108-112 9066677-4 1997 Our results show that short term treatment of MDR cells with 1-50 microM N-ethylmaleimide led to a concentration dependent increase in P-gp photoaffinity labeling with iodoaryl-azidoparazosin (IAAP). Ethylmaleimide 73-89 ATP binding cassette subfamily B member 1 Homo sapiens 135-139 9066677-7 1997 Thus, the observed increase in P-gp photolabeling with IAAP in N-ethylmaleimide treated cells is not due to photolabeling at different sites. Ethylmaleimide 63-79 ATP binding cassette subfamily B member 1 Homo sapiens 31-35 9066677-8 1997 Incubation of MDR cells with [14C] N-ethylmaleimide showed that P-gp is directly modified at several Cysteine residues, as found from a complete proteolytic digestion of [14C] Nethylmaleimide labeled P-gp. Ethylmaleimide 36-51 ATP binding cassette subfamily B member 1 Homo sapiens 64-68 9066677-8 1997 Incubation of MDR cells with [14C] N-ethylmaleimide showed that P-gp is directly modified at several Cysteine residues, as found from a complete proteolytic digestion of [14C] Nethylmaleimide labeled P-gp. Ethylmaleimide 36-51 ATP binding cassette subfamily B member 1 Homo sapiens 200-204 9066677-8 1997 Incubation of MDR cells with [14C] N-ethylmaleimide showed that P-gp is directly modified at several Cysteine residues, as found from a complete proteolytic digestion of [14C] Nethylmaleimide labeled P-gp. Ethylmaleimide 176-191 ATP binding cassette subfamily B member 1 Homo sapiens 64-68 9066677-8 1997 Incubation of MDR cells with [14C] N-ethylmaleimide showed that P-gp is directly modified at several Cysteine residues, as found from a complete proteolytic digestion of [14C] Nethylmaleimide labeled P-gp. Ethylmaleimide 176-191 ATP binding cassette subfamily B member 1 Homo sapiens 200-204 9066677-11 1997 Interestingly, N-ethylmaleimide increases P-gp phosphorylation by inhibiting the turnover of Pgp phosphates. Ethylmaleimide 15-31 ATP binding cassette subfamily B member 1 Homo sapiens 42-46 9066677-13 1997 Taken together, the results of this study suggest that N-ethylmaleimide potentiates P-gp photolabeling with IAAP by inhibiting P-gp ATPase thereby increasing the local concentration of IAAP in intact MDR cells. Ethylmaleimide 55-71 ATP binding cassette subfamily B member 1 Homo sapiens 84-88 9066677-13 1997 Taken together, the results of this study suggest that N-ethylmaleimide potentiates P-gp photolabeling with IAAP by inhibiting P-gp ATPase thereby increasing the local concentration of IAAP in intact MDR cells. Ethylmaleimide 55-71 ATP binding cassette subfamily B member 1 Homo sapiens 127-131 9066677-14 1997 Furthermore, inhibition of P-gp ATPase by N-ethylmaleimide does not lead to conformational changes that affects P-gp drug binding. Ethylmaleimide 42-58 ATP binding cassette subfamily B member 1 Homo sapiens 27-31 7608182-6 1995 Transport was prevented by omission of Mg2+, by substitution of nonhydrolyzable adenylyl-beta,gamma-imidodiphosphate for ATP, by inhibition of the ATPase activity of P-glycoprotein with vanadate and N-ethylmaleimide, and by the chemosensitizers verapamil and amiodarone. Ethylmaleimide 199-215 ATP binding cassette subfamily B member 1 Homo sapiens 166-180 7559432-1 1995 The ATPase activity of P-glycoprotein is inactivated by N-ethylmaleimide (NEM), which is postulated to modify cysteine residues within either of the homology A consensus sequences for nucleotide binding (GNSGCGKS and GSSGCGKS, respectively) (Al-Shawi, M. K., Urbatsch, I. L., and Senior, A. E. (1994) J. Biol. Ethylmaleimide 56-72 ATP binding cassette subfamily B member 1 Homo sapiens 23-37 7559432-1 1995 The ATPase activity of P-glycoprotein is inactivated by N-ethylmaleimide (NEM), which is postulated to modify cysteine residues within either of the homology A consensus sequences for nucleotide binding (GNSGCGKS and GSSGCGKS, respectively) (Al-Shawi, M.
