Background Information
ARPP-19, a 19-kDa cAMP-regulated phosphoprotein, plays a role in regulating mitosis. Initiation and maintenance of mitosis require the activation of protein kinase cyclin B-Cdc2 and the inhibition of protein phosphatase 2A (PP2A). When phosphorylated by protein kinase Greatwall (Gwl), ARPP-19 associate with and inhibit PP2A, thus promoting mitotic entry. ARPP-19 may be an important link between nerve growth factor (NGF) signaling and post-transcriptional control of neuronal gene expression such as GAP-43.
