    Abstract:
    The regional distribution of a novel pituitary protein (7B2) in the rat brain was studied using a specific and sensitive radioimmunoassay. Immunoreactive (IR)-7B2 was distributed throughout the brain, with the highest concentrations in the pituitary, hypothalamus and basal ganglia. Immunoreactive 7B2 from the brain and other tissues had an apparent molecular weight of around 20,000 as estimated by SDS-polyacrylamide gel electrophoresis as observed with other tissues. In homozygous Brattleboro rats which do not synthesize vasopressin or its associated neurophysin, IR-7B2 levels in the brain and pituitary gland were shown to be similar to those of control animals. Furthermore, the molecular weight of 7B2 in the brain and pituitary gland of homozygous Brattleboro rats was similar to that of control animals.
