He. Milner et al., THE IN-SITU SIZE OF THE DOPAMINE TRANSPORTER IS A TETRAMER AS ESTIMATED BY RADIATION INACTIVATION, Biochimica et biophysica acta. Biomembranes, 1190(1), 1994, pp. 185-187
Radiation inactivation analysis of the mazindol-sensitive binding of t
he dopamine transporter inhibitor, [H-3]GBR-12935 to canine striatal m
embranes yielded a radiation inactivation target size of 278 +/- 16 kD
a. This result, in conjunction with other findings in the literature d
emonstrating that the molecular mass of the dopamine transporter is si
milar to 70 kDa, suggests that the native form of the dopamine carrier
in the neuronal membranes is a tetrameric assembly of identical 70 kD
a subunits.
