Abstract: An olfactory system-specific protein of 24 kDa (N24) was identified in kokanee salmon (Oncorhynchus nerka) by the comparison of proteins restricted to the olfactory system (olfactory epithelium, olfactory nerve and olfactory bulb) with those found in other parts of the brain (telencephalon, optic tectum, cerebellum, hypothalamus) and hypophysis. A polyclonal antibody to N24 was raised in a rabbit, and the specificity of the antiserum was examined by Western blotting analysis; the antiserum recognized only one 24 kDa band in the olfactory system but not in other parts of the brain in kokanee salmon, sockeye salmon (O. nerka), masu salmon (O. masou) and chum salmon (O. keta). Immunocytochemical analysis revealed that positive immunoreactivity occurred exclusively in the olfactory nerve and in some olfactory neuroepithelial cells. Both at the time of imprinting of maternal stream odorants and at the time of homing to the maternal stream, the immunoreactivity of N24 in fish in the maternal stream was stronger than that in seawater fish. The present study indicates that an olfactory system-specific protein may be importantly related to both imprinting and homing mechanisms in salmonids.
