The localization of Ca2+/calmodulin-dependent protein kinase IV (CaM kinase IV) in the mature and developing rat retina was examined by immunohistochemistry and in situ hybridization histochemistry. In immunoblotting analysis, a single band of 63 kDa was detected in the crude homogenate of the adult rat retina, indicating the presence of the alpha polypeptide of CaM kinase IV. In the adult rat retina, most of the bipolar cells and some ganglion cells exhibited CaM kinase IV-immunoreactivity. By immunoelectron microscopy, the immunoreactive product was predominantly localized to the nucleus of immunoreactive cells. In the developing rat retina, immunoreactive bipolar cells were first detected on postnatal day 10 (P10), and they were abundant on P14. All these findings suggest that CaM kinase IV may participate in some yet unknown nuclear Ca(2+)-relating visual signal-processing of the retina.

D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012165	Retinal Ganglion Cells	Neurons of the innermost layer of the retina, the internal plexiform layer. They are of variable sizes and shapes, and their axons project via the OPTIC NERVE to the brain. A small subset of these cells act as photoreceptors with projections to the SUPRACHIASMATIC NUCLEUS, the center for regulating CIRCADIAN RHYTHM.
