Summary: Enables DNA-binding transcription factor binding activity and chromatin binding activity. Involved in several processes, including imaginal disc-derived wing margin morphogenesis; positive regulation of imaginal disc growth; and regulation of signal transduction. Located in nucleus and polytene chromosome. Part of transcription repressor complex. Is expressed in several structures, including anterior endoderm; eye disc; ganglia; germline cell; and larval muscle system. Used to study sensory system disease. Human ortholog(s) of this gene implicated in Pierpont syndrome; Y-linked deafness 2; autosomal dominant intellectual developmental disorder 41; and congenital nongoitrous hypothyroidism 8. Orthologous to human TBL1XR1 (TBL1X/Y related 1); TBL1X (transducin beta like 1 X-linked); and TBL1Y (transducin beta like 1 Y-linked). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Study proposes that the interplay of Crb expression in the DV boundary and ubiquitin-dependent Crb downregulation by Ebi provides a mechanism for the maintenance of Notch signaling during wing development.
Title: Ebi modulates wing growth by ubiquitin-dependent downregulation of Crumbs in Drosophila.
Results offer clear in vivo evidence that the Ebi-containing co-repressor complex acts in a distinct manner to regulate transcription that is required for modulating the output of various processes during Drosophila development.
Title: Cellular Defense and Sensory Cell Survival Require Distinct Functions of ebi in Drosophila.
The antagonistic function of ebi against the Polycomb group silencing complex plays a role in the G1/S phase transition.
Title: Ebi alleviates excessive growth signaling through multiple epigenetic functions in Drosophila.
EBI acts to activate (de-repress) transcription of Notch target genes important for Drosophila wing growth by functioning as a corepressor/coactivator exchange factor for SU(H).
Title: Genetic characterization of ebi reveals its critical role in Drosophila wing growth.
Ebi/AP-1 suppresses basal transcription levels of apoptotic genes and thereby protects sensory neurons from degeneration
Title: Ebi/AP-1 suppresses pro-apoptotic genes expression and permits long-term survival of Drosophila sensory neurons.
Ebi directly interacts with the Snail repressor and regulates Snail repressor function in the early embryo and in tissue culture cells.
Title: Drosophila Ebi mediates Snail-dependent transcriptional repression through HDAC3-induced histone deacetylation.
An EGFR/Ebi/Sno pathway promotes delta expression by inactivating Su(H)/SMRTER repression during inductive notch signaling.
