Expression detected in adult brain, testis and spleen. In the testis, expressed in the germ cells of the seminiferous epithelium, in elongating spermatids and in spermatozoa. Expressed throughout the brain with highest levels in regions of the cerebral cortex, hippocampus, diencephalon, pons, medulla and cerebellum. In the embryo, expressed in the developing posterior central nervous system. First seen in the ectoderm lateral to the primitive streak, later it encompasses the neural plate. Starting at day 9.5 pc, expressed in distinct areas of spinal cord, hindbrain, midbrain and forebrain.2 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence.
