Specifically expressed during neocortex and cerebellum development. First expressed in the cerebral cortex after the preplate stage (>E12). At embryonic stage 15.5 dpc and up to 17.5 dpc, it is expressed in cortical plate and in the marginal zone, whereas in adult brain, it is present in all cortical and subcortical regions of the brain. In the developing cerebellum, expressed in the intermediate zone at stage 17.5 dpc, in the molecular layer in newborn, and in the granular as well as molecular layer in adult. In the adult brain, expression in interneurons is also observed. Truncated N-terminus. Truncated N-terminus. Truncated N-terminus.
