Sagittal band expression of COUP-TF2 gene in the developing cerebellum.
In the developing cerebellum, the medio-lateral compartmentalization of the adult cerebellum is preceded by the transient expression of factors which divide the cortex into similar parasagittal stripes. Here we report that COUP-TF2, an orphan member of the nuclear receptor family which suppresses RA actions by forming heterodimers with RXR, shows a pattern of sagittal bands in developing mouse cerebellum. The band pattern changes according to the developmental stage. At embryonic day 13 it is expressed in the lateral half of the cerebellum, but at later stages the expression is divided into several parasagittal bands. By postnatal day 5 the COUP-TF2 expression substantially decreases to low, but detectable, levels.
