The splicing regulator Rbfox1 (A2BP1) controls neuronal excitation in the mammalian brain.

Nature genetics | May 29, 2011

The Rbfox family of RNA binding proteins regulates alternative splicing of many important neuronal transcripts, but its role in neuronal physiology is not clear. We show here that central nervous system-specific deletion of the gene encoding Rbfox1 results in heightened susceptibility to spontaneous and kainic acid-induced seizures. Electrophysiological recording revealed a corresponding increase in neuronal excitability in the dentate gyrus of the knockout mice. Whole-transcriptome analyses identified multiple splicing changes in the Rbfox1(-/-) brain with few changes in overall transcript abundance. These splicing changes alter proteins that mediate synaptic transmission and membrane excitation. Thus, Rbfox1 directs a genetic program required in the prevention of neuronal hyperexcitation and seizures. The Rbfox1 knockout mice provide a new model to study the post-transcriptional regulation of synaptic function.

UCSC Genome Browser

A collection of genomes which include reference sequences and working draft assemblies, as well as a variety of tools to explore these sequences. The Genome Browser zooms and scrolls over chromosomes, showing the work of annotators worldwide. The Gene Sorter shows expression, homology and other information on groups of genes that can be related in many ways. Blat quickly maps your sequence to the genome. The Table Browser provides access to the underlying database. VisiGene lets you browse through a large collection of in situ mouse and frog images to examine expression patterns. Genome Graphs allows you to upload and display genome-wide data sets. Also provided is a portal to the Encyclopedia of DNA Elements (ENCODE) and Neandertal projects.
