title: Proline binding to mouse brain synaptosomes.
abstract: L-proline has been shown to exert a variety of physiological and behavioral effects that are consistent with its possible role as a neuromodulator in the mammalian brain. The binding of l-proline to mouse brain synaptosomes has been partially characterized. Preliminary kinetic analysis shows the presence of at least two binding sites in the submicromolar range, and one in the nanomolar range. While more detailed studies are necessary as to determine the biological significance of proline binding to mouse brain synaptosomes, these results further support the possible role of proline as a neuromodulator.
