title: Localization of opioid-binding cell adhesion molecule (OBCAM) in adult rat brain.
abstract: We investigated the tissue distribution and brain localization of opioid-binding cell adhesion molecule (OBCAM) in the adult rats by immunoblotting and immunohistochemistry using a monoclonal anti-OBCAM peptide antibody that is specific for OBCAM. OBCAM was preferentially expressed in the central nervous system (CNS) and at a very low level in the spleen. Within the brain, OBCAM was distributed in almost all the gray matter, but little or no immunoreactive OBCAM was found in the white matter. Morphologically, the distribution pattern of OBCAM immunoreactivity was very similar to that of synaptophysin, suggesting a role in the synaptic machinery.
