Genome-wide ChIP-seq in mouse embryonic day 16.5 forebrains shows Auts2 predominantly binds promoters of highly expressed neurodevelopmental genes, acting as a transcriptional activator; non-promoter Auts2-bound regions overlap developing brain enhancer marks near ASD-implicated genes including NRXN1 and ATP2B2. |

AUTS2 isoforms differentially regulate transcription and neuronal differentiation: the long isoform interacts with polycomb proteins PCGF3 and PCGF5 (identified by yeast two-hybrid), while both isoforms interact with splicing factor SF3B1. The first exons of the long isoform function as a transcriptional repressor, while the short isoform region acts as a transcriptional activator. PCGF3 expression levels modulate whether the long isoform activates or represses transcription. A shift from long to short isoform expression accompanies initiation of neuronal differentiation. |

AUTS2 forms part of non-canonical PRC1 complexes (ncPRC1.3 and ncPRC1.5) that activate rather than repress transcription; AUTS2 interacts with P300 through its HX repeat domain, and mutations in this domain disrupt the AUTS2-P300 interaction. Nuclear respiratory factor 1 (NRF1) is required for ncPRC1.3 recruitment to chromatin, and absence of AUTS2 or HX domain mutation causes misregulation of developmental genes and impaired motor neuron differentiation of mouse embryonic stem cells. |

WDR68 is an integral component of the PRC1-AUTS2 complex and is required for PRC1-AUTS2-mediated transcriptional activation; deletion of Wdr68 in mouse ESCs leads to defects in neuronal differentiation and downregulation of neuronal differentiation genes that are targets of the PRC1-AUTS2 complex. |

AUTS2 forms a novel PRC1-independent complex with WDR68 and SKI (the AWS complex) specifically in neuronal progenitors; this complex promotes neuronal differentiation by recruiting the CUL4 E3 ubiquitin ligase complex to mediate poly-ubiquitination and proteasomal degradation of phosphorylated SMAD1/5/9, thereby inhibiting BMP signaling. |

AUTS2 associates with multiple RNA-binding and RNA-metabolism proteins in neonatal mouse cerebral cortex (identified by proteomics), and AUTS2-containing protein complexes bind specific RNA transcripts (identified by RNA immunoprecipitation and sequencing). Deletion of all major AUTS2 isoforms by conditional excision of exon 15 caused breathing abnormalities, neonatal lethality, dentate gyrus hypoplasia with agenesis of hilar mossy neurons, abnormal EEG spiking, and dysregulation of AUTS2-associated RNA transcripts. |

Auts2 deletion causes postnatal dentate gyrus (DG) hypoplasia by acting as a transcription repressor to regulate neural cell migration in postnatal DG development; this DG hypoplasia disrupts the SuM-DG-CA3 neural circuit and causes social recognition deficit, which can be rescued by pharmacological correction of DG-CA3 synaptic transmission or chemo/optogenetic activation of the SuM-DG circuit. |

AUTS2 cooperates with PRC2 to repress transcription of target genes (including Robo1) in intermediate progenitor cells (IPCs) by maintaining H3K27me3 at their transcriptional start sites; loss of AUTS2 reduces H3K27me3, increases Robo1 expression, suppresses IPC division, reduces upper-layer neurons, and causes microcephaly in mice. |
