Abstract

It was first shown in the PR (PRDI-BF1 and RIZ homology) domain family proteins that the PR domain has homology to the SET (Su(var)3-9, Enhancer-of-zeste and Trithorax) domain, a catalytic domain of the histone lysine methyltransferases. Recently, there are many reports that the PR domain proteins have important roles in development and/or cell differentiation. In this report, we show the expression patterns of one of the mouse PR domain proteins, Prdm8, in the developing central nervous system. In the developing retina, Prdm8 expression was detected in postmitotic neurons in the inner nuclear layer and the ganglion cell layer, and its expression became restricted predominantly to the rod bipolar cells when retinogenesis was completed. In the developing spinal cord, Prdm8 was expressed first in the progenitor populations of ventral interneurons and motor neurons, and later in a subpopulation of interneurons. In the developing brain, Prdm8 expression was observed in postmitotic neurons in the intermediate zone and the cortical plate. In the postnatal brain, Prdm8 was expressed mainly in layer 4 neurons of the cerebral cortex. These results show that Prdm8 expression is tightly regulated in a spatio-temporal manner during neural development and mainly restricted to postmitotic neurons, except in the spinal cord.
