title: L-dopa binding sites in rodent melanoma cells.
abstract: Rapid, saturable, specific and stereoselective binding of L-dopa to crude membranes and purified nuclei from rodent amelanotic melanoma cells is reported. Cross-linking of [3H]dopa to melanoma cell surface emphasized proteins of approx. 55, 30, 25 and less than 20 kDa. It is suggested that these binding sites may regulate melanocyte activity.
