Abstract

Mutations in the human Crumbs homologue 1 (CRB1) gene cause severe retinal dystrophies. CRB1 is homologous to Drosophila Crumbs, a protein essential for establishing and maintaining epithelial polarity. We have isolated the mouse orthologue, Crb1, and analyzed its expression pattern in embryonic and post-natal stages. Crb1 is expressed exclusively in the eye, and the central nervous system. In the developing eye, expression of Crb1 is detected in the retinal progenitors, and later on becomes restricted to the differentiated photoreceptor cells where it remains active up to the adult stage. In the developing neural tube, expression of Crb1 is restricted to its most ventral structures, coinciding with the expression domain of Nkx2.2. In the adult brain, Crb1 expression is defined to areas where the production and migration of neurons occurs in adulthood.
