However, the precise and coordinated transcriptional network activity defining neuronal identity is still not understood. Here, we show that genetic depletion of the basic helix-loop-helix (bHLH) transcription factor E2A splice variant E47 increased the number of Tbr1-positive deep layer and Satb2-positive upper layer neurons at E14.5, while depletion of the alternatively spliced E12 variant did not affect layer-specific neurogenesis. While ChIP-Seq identified a big overlap for E12- and E47-specific binding sites in embryonic NSCs, including sites at the cyclin-dependent kinase inhibitor (CDKI) Cdkn1c gene locus, RNA-Seq revealed a unique transcriptional regulation by each splice variant. E47 activated the expression of the CDKI Cdkn1c through binding to a distal enhancer. Finally, overexpression of E47 in embryonic NSCs in vitro impaired neurite outgrowth and E47 overexpression in vivo by in utero electroporation disturbed proper layer-specific neurogenesis and upregulated p57(KIP2) expression. Overall, this study identified E2A target genes in embryonic NSCs and demonstrates that E47 regulates neuronal differentiation via p57(KIP2).","lang":"eng"}],"date_created":"2018-12-11T11:48:36Z","external_id":{"isi":["000414025600007"]},"status":"public","author":[{"full_name":"Pfurr, Sabrina","last_name":"Pfurr","first_name":"Sabrina"},{"full_name":"Chu, Yu","first_name":"Yu","last_name":"Chu"},{"full_name":"Bohrer, Christian","last_name":"Bohrer","first_name":"Christian"},{"full_name":"Greulich, Franziska","first_name":"Franziska","last_name":"Greulich"},{"full_name":"Beattie, Robert J","id":"2E26DF60-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8483-8753","first_name":"Robert J","last_name":"Beattie"},{"last_name":"Mammadzada","first_name":"Könül","full_name":"Mammadzada, Könül"},{"full_name":"Hils, Miriam","last_name":"Hils","first_name":"Miriam"},{"full_name":"Arnold, Sebastian","first_name":"Sebastian","last_name":"Arnold"},{"first_name":"Verdon","last_name":"Taylor","full_name":"Taylor, Verdon"},{"full_name":"Schachtrup, Kristina","last_name":"Schachtrup","first_name":"Kristina"},{"full_name":"Uhlenhaut, N Henriette","first_name":"N Henriette","last_name":"Uhlenhaut"},{"full_name":"Schachtrup, Christian","last_name":"Schachtrup","first_name":"Christian"}],"publication_status":"published","language":[{"iso":"eng"}],"publication":"Development","_id":"805","scopus_import":"1","type":"journal_article","page":"3917 - 3931","doi":"10.1242/dev.145698","intvolume":"       144","citation":{"chicago":"Pfurr, Sabrina, Yu Chu, Christian Bohrer, Franziska Greulich, Robert J Beattie, Könül Mammadzada, Miriam Hils, et al. “The E2A Splice Variant E47 Regulates the Differentiation of Projection Neurons via P57(KIP2) during Cortical Development.” <i>Development</i>.
