Summary: Enables sequence-specific double-stranded DNA binding activity and transcription coactivator binding activity. Involved in several processes, including adult feeding behavior; regionalization; and regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including denticle field anlage; epithelium; germline cell; organism subdivision; and trichome field. Human ortholog(s) of this gene implicated in posterior polymorphous corneal dystrophy 1. Orthologous to several human genes including OVOL1 (ovo like transcriptional repressor 1).

OVO positively regulates essential maternal pathways by binding near the transcriptional start sites in the Drosophila female germline.
Title: OVO positively regulates essential maternal pathways by binding near the transcriptional start sites in the Drosophila female germline.
Here, the authors show that a molecular complex identified in Drosophila epidermal differentiation, comprising Mlpt peptides, ubiquitin-ligase Ubr3 and transcription factor Shavenbaby (Svb), represents an ancient developmental module required for early insect embryo patterning.
Title: The mlpt/Ubr3/Svb module comprises an ancient developmental switch for embryonic patterning.
Transcription sites of the full svb cis-regulatory region inserted into a different chromosome colocalized with the svb locus, increasing Ubx concentration, the transcriptional output of svb, and partially rescuing the phenotype.
Title: Multi-enhancer transcriptional hubs confer phenotypic robustness.
Shavenbaby and Yorkie mediate Hippo signaling to protect adult stem cells from apoptosis
Title: Shavenbaby and Yorkie mediate Hippo signaling to protect adult stem cells from apoptosis.
Co-expressing ectopic SoxN with svb rescued diverse denticle morphologies. Conversely, removing SoxN activity eliminated the residual denticles found in svb mutant embryos. Furthermore, several known Svb target genes are also activated by SoxN, and we have discovered two novel target genes of SoxN that are expressed in denticle-producing cells and that are regulated independently of Svb.
Title: SoxNeuro and Shavenbaby act cooperatively to shape denticles in the embryonic epidermis of Drosophila.
Report the high-resolution functional dissection of a robust enhancer of the shavenbaby gene that has contributed to morphological evolution. We found that robustness is encoded by many binding sites for the transcriptional activator Arrowhead and that, during evolution, some of these activator sites were lost, weakening enhancer activity.
Title: Evolved Repression Overcomes Enhancer Robustness.
Hox protein Ultrabithorax (Ubx) in complex with its cofactor Extradenticle (Exd) bound specifically to clusters of very low affinity sites in enhancers of the shavenbaby gene of Drosophila. These low affinity sites conferred specificity for Ubx binding in vivo, but multiple clustered sites were required for robust expression when embryos developed in variable environments.
Title: Low affinity binding site clusters confer hox specificity and regulatory robustness.
Multiple shavenbaby enhancers drive overlapping patterns of expression in the embryo.
Title: The structure and evolution of cis-regulatory regions: the shavenbaby story.
study shows peptides of 11 to 32 amino acids encoded by polished rice(pri)sORF gene control epidermal differentiation by modifying Shavenbaby (Svb); Pri peptides trigger amino-terminal truncation of Svb which converts Svb from a repressor to an activator
Title: Small peptides switch the transcriptional activity of Shavenbaby during Drosophila embryogenesis.
Results show that the embryonic expression of dsc73 requires Shavenbaby, a transcription factor regulating cuticle formation.
Title: Expression of the Drosophila secreted cuticle protein 73 (dsc73) requires Shavenbaby.
