Querkopf, a MYST family histone acetyltransferase, is required for normal cerebral cortex development

Abstract

In order to find, and mutate, novel genes required for regulation of neurogenesis in the cerebral cortex, we performed a genetic screen in mice. As the result of this screen, we created a new mouse mutant, querkopf. The querkopf mutation is due to an insertion into a MYST family histone acetyltransferase gene. Mice homozygous for the querkopf mutation have craniofacial abnormalities, fail to thrive in the postnatal period and have defects in central nervous system development. The defects in central nervous system development are particularly prominent in the cerebral cortex, which is disproportionally smaller than in wild-type mice. A large reduction in the size of the cortical plate was al..
