Research Abstract

We performed immunohistochemical analysis and found that JSAP1, a scaffold protein for JNK signaling pathways, is expressed predominantly in the post-mitotic granule cell precursors (GCPs) of the inner external granular layer. We also showed that when stimulated by FGF receptor, JSAP1 translocates to the plasma membrane, where it recruits JNK and facilitates the activation of JNK, leading to the differentiation of cerebellar GCPs. Furthermore, we found that JSAP1-JNK signaling promotes the cell cycle exit and differentiation of cerebellar GCPs.
