pp60c-src is developmentally regulated in the neural retina.

Abstract

We have localized normal cellular pp60c-src in the developing chick neural retina by immunocytochemical staining using antisera raised against bacterially expressed pp60v-src, the src gene product of Rous sarcoma virus. pp60c-src was expressed in developing retinal neurons at the onset of differentiation. Expression of pp60c-src persisted in mature neuronal cells that were postmitotic, fully differentiated, and functional. pp60c-src immunoreactivity was localized within processes and cell bodies of ganglion neurons, processes of rods and cones, and in some but not all neurons of the inner nuclear layer. Protein kinase assays and Western transfer analyses identified the immunoreactive protein as pp60c-src, and confirmed that its expression occurs at the time the first neuronal cells in the retina differentiate. We conclude from these studies that pp60c-src is the product of a developmentally regulated gene that is more important in neuronal differentiation or function than cell proliferation.
