Two molecular forms of ChAT activity after isoelectric focusing, homogenates of Chats1 lead to a single form, and ofĬhats2 to two forms shifted to higher-than-normal pI (Salvaterra and McCaman, 1985) these two conditional Cha mutationsĪlso cause ChAT activity to have accentuated thermolability in Synapses in this pathway are cholinergic (Gorczyca and Hall,ġ984, J.
