Nicotine 82-90 proteasome subunit alpha type-7-like Nicotiana tabacum 18-24 32738308-4 2020 The nAChRs that contain the alpha4 and beta2 subunits, often in combination with the alpha6 subunit, are particularly important for nicotine"s ability to increase midbrain dopamine neuron firing rates and phasic burst firing. Nicotine 132-140 proteasome subunit alpha type-7-like Nicotiana tabacum 28-34
