Expression of coiled-coil protein 1, a novel gene downstream of FGF2, in the developing brain.

Fibroblast growth factor 2 (FGF2) plays an important role in cortical development. However, the genes downstream of FGF2 that mediate its effect are largely unknown. We have performed a microarray screening of genes regulated by FGF2 using primary cortical neuron culture derived from embryonic day 14.

Isolation and characterization of murine Cds (CDP-diacylglycerol synthase) 1 and 2.

Phototransduction in Drosophila is a phosphoinositide-mediated signalling pathway. Phosphatidylinositol 4,5-bisphosphate (PIP2) plays a central role in this process, and its levels are tightly regulated. A photoreceptor-specific form of the enzyme CDP-diacylglycerol synthase (CDS), which catalyzes the formation of CDP-diacylglycerol from phosphatidic acid, is a key regulator of the amount of PIP2 available for signalling.

FGFR3 regulates brain size by controlling progenitor cell proliferation and apoptosis during embryonic development.

Mice with the K644E kinase domain mutation in fibroblast growth factor receptor 3 (Fgfr3) (EIIa;Fgfr3(+/K644E)) exhibited a marked enlargement of the brain. The brain size was increased as early as E11.5, not secondary to the possible effect of Fgfr3 activity in the skeleton.
