Abstract

Raf protein kinases and protein kinase C belong to serine/threonine-specific proteins in the cytoplasin, and are similar to each other in functional structure and the aspect of the distribution of celI. The distribution of raf protein kinase in the cerebrum of Geoclemys reevesfi as studied by using the antibodies against a-raf and c-raf protein kinase which induce the expression of raf fainily oncogenes. In general, raf protein kinases were distributed in such restricted regions as the general pallium, hippocampal formation, pdmordiuin hippocampi,nucleus of lateral olfactory tract, basal amygdaloid nucleus, and bed of stria terminalis. Immunological labeling of c-raf protein kinase was more widespread than that of a-raf. However, the intensity of the labeling of c-raf was lower than that of a-raf. The spherical cells of basal amygdaloid nucleus is a ring-like form, because only the cytoplasm was imunolabeled. Especially, c-raf protein kinase occurred in the cells which contained protein kinase C abundandy such as pyramidal cells and Purkinje cells. This suggests that a- and e-raf protein kinases may synegistically induce carclnoma with myc gene which is activated by protein kinase C.
