摘要:
Abstract:The effect of unilateral labyrinthectomy followed by the process of vestibular compensation on the incorporation of radioactive phosphate into frog brain proteins was investigated. Phosphoproteins were analyzed by sodium dodecyl sulfate‐polyacrylamide gel electrophoresis followed by autoradiography. The present data show that unilateral labyrinthectomy affects the incorporation of32P into various frog brain proteins. In particular, the phosphorylation of a 20‐kDa protein appeared enhanced during early stages of vestibular compensation (4–12 days). This 20‐kDa protein was shown to be immunologically related to myelin basic protein and its phosphorylation was regulated by an endogenous calcium/calmodulin‐dependent protein kinase. These data might indicate that in addition to neuronal components, components of glial origin are also involved in biochemical events that lead to functional recovery after neurona
