Distinct cellular localization of membrane-bound and soluble forms of catechol-O-methyltransferase in brain.

The cellular localization of the two forms of catechol-O-methyltransferase (COMT) was investigated by measuring their activities in rat striatum following unilateral stereotaxic injection of kainic acid, which causes degeneration of striatal neurons followed by proliferation of astroglial cells. Membrane-bound COMT activity was decreased in the lesioned… CONTINUE READING
