May regulate apoptosis of neural progenitor cells during their differentiation. Expressed in Purkinje cells of the cerebellum and neurons in the CA3 region of the hippocampus. Also detected in non-neural tissues including mesenchymal layer adjacent to epithelium in developing bronchi of the lung, the epithelium of the stomach as well as cells in the liver. Expressed in the cerebral cortex at 14 dpc (at protein level). Expressed in the walls of the third and fourth ventricles, and in the hippocampus during development. The protein kinase domain is predicted to be catalytically inactive. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Extended N-terminus. Extended N-terminus.
