Expressioni

Tissue specificityi

Present in all tissues tested, with highest protein levels in brain and adrenal.

Developmental stagei

On embryonic days 15 (E15) and E18, expressed in the cortical plate of the cerebrum. On postnatal days 0 (P0) and P7, a moderate expression is seen in the cerebral neocortex, hippocampal pyramidal and dentate granule cell layers. In the cerebellum, expressed in the cerebellar Purkinje cells. On P14, a decreased expression is seen throughout the brain. On P21, expression is seen in the cerebellar Purkinje cells, dentate granule cells and the hippocampal pyramidal cells.1 Publication
