P1150A | mutant MRP1 exhibits selectively increased estradiol glucuronide and methotrexate transport as well as altered interactions with ATP, the mutant displays very a low level of substrate-independent vanadate-induced trapping of [alphalpha32P]8N3ADP due to enhanced ADP release following ATP hydrolysis rather than a reduction in ATP hydrolysis itself. [alpha32P]8N3ADP trapping by MRP1-P1150A can be increased by using Ni2+ instead of Mg2+, and by decreasing temperature; however, the transport properties of the mutant remain unchanged | Homo sapiens |
P1150G | mutant MRP1 exhibits selectively increased estradiol glucuronide and methotrexate transport as well as altered interactions with ATP, the mutant displays very a low level of substrate-independent vanadate-induced trapping of [alpha32P]8N3ADP due to enhanced ADP release following ATP hydrolysis rather than a reduction in ATP hydrolysis itself | Homo sapiens |
P1150I | mutant MRP1 exhibits selectively increased estradiol glucuronide and methotrexate transport as well as altered interactions with ATP, the mutant displays very a low level of substrate-independent vanadate-induced trapping of [alpha32P]8N3ADP due to enhanced ADP release following ATP hydrolysis rather than a reduction in ATP hydrolysis itself | Homo sapiens |
P1150L | mutant MRP1 exhibits selectively increased estradiol glucuronide and methotrexate transport as well as altered interactions with ATP, the mutant displays very a low level of substrate-independent vanadate-induced trapping of [alpha32P]8N3ADP due to enhanced ADP release following ATP hydrolysis rather than a reduction in ATP hydrolysis itself | Homo sapiens |
P1150V | mutant MRP1 exhibits selectively increased estradiol glucuronide and methotrexate transport as well as altered interactions with ATP, the mutant displays very a low level of substrate-independent vanadate-induced trapping of [alpha32P]8N3ADP due to enhanced ADP release following ATP hydrolysis rather than a reduction in ATP hydrolysis itself | Homo sapiens |
